A proxy server manages Internet traffic at the request of clients that are usually on a local area network. Special Internet application protocols are used for this purpose. These are primarily HTTP and possibly Gopher and FTP; the document always begins correspondingly with http, gopher or ftp Link Box Print
A server that performs network operations in lieu of other systems on the network. Proxy Servers are most often used as parts of a firewall to mask the identity of users inside a corporate network yet still provide access to the Internet. When a user connects to a proxy server, via a web browser or other networked application, he submits commands to the proxy server. The server then submits those same commands to the Internet, yet without revealing any information about the system that originally requested the information. Proxy servers are an ideal way to also have all users on a corporate network channel through one point for all external communications. Proxy servers can be configured to block certain kinds of connections and stop some hacks.
A device that processes and filters all Internet Protocol (IP) packets that are directed to it and decides which protocols and services can be served out of its cache. Proxy servers tend to offer the greatest range of protocol and caching support since they cache Hypertext Transport Protocol (HTTP), File Transfer Protocol (FTP) and, in some cases, streaming content such as audio and video. Each workstation addresses the proxy server directly by setting specific parameters in each browser on each workstation. See HTTP and FTP.
A proxy server is a kind of buffer between your computer and the Internet resource(s) you are accessing. The data you request come to the proxy first, and only then it transmits the data to you. A proxy server receives a request for an Internet service (such as a web page request) from a user. If the proxy server is also a cache server, it can use its local cache of previously downloaded web pages to provide the page without forwarding the request to the Internet. If the page is not in the cache, the proxy server uses one of its own IP addresses to request the page from the server on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it to the user.
A computer that acts as an intermediary between your computer, and the computer you want to access. Used to provide Web access from behind a firewall or security computer.
This server allows UCSD Faculty, staff and students access to UCSD's electronic resources through UCSD's network from off campus sites. The server authenticates user as a UCSD affiliate.
An Internet server dedicated to improve Internet performance.
A computer or other network device used to pass requests, handle functions or information (such as requests to view web sites) on behalf of one or more other computers; application-specific proxies are frequently deployed within firewall configurations to enhance security.
A computer server that sits on the boundary between the external network (e.g., the Internet) and an internal network which is connected to both networks. The Proxy Server serves as a proxy to which communications are sent from both within and outside the organization; translates between internal/external identities (e.g., internal/external e-mail addresses); and controls Authorization to communicate (e.g., e-mail account limited to internal use only or controlling which internal servers an external message may communicate).
Computer software that enables the Collegeâ€(tm)s computer network to recognize your computer off campus. You must have your Internet browser set up to use the proxy server in order to gain access to the Libraryâ€(tm)s research databases while off campus.
A server can store a page remotely to speed loading time. This is another killer for those who want to evaluate traffic.
A proxy server permits access between machines behind a firewall and external networks collecting and relaying communications between the two. The proxy server gives the illusion that the communication is direct.
The server middle man, a proxy server relays messages between a client and the server the client is trying to use. Proxy servers store results to reduce demands on the main servers and to provide quicker replies to clients. Proxy servers are commonly established on LANs.
A proxy server acts as a diversion between a local computer and a remote system that you are trying to connect to. If set up, all data will be sent through the proxy server on its way to or from the local computer. Queen’s uses a proxy server to allow users who are off campus to connect to Queen’s resources, such as Exam Bank, QCAT and WebCT.
A server that acts as both a client and a server to make requests on behalf of another user agent. The primary role of a proxy server is to ensure that a request generated by a UA is passed to another entity that is closer to the destination user.
A server that works as a barrier between an internal network (intranet) and the Internet. Proxy servers can work with firewalls, which help keep other people on the Internet from gaining access to confidential information on the intranet. A proxy server also allows the caching of Web pages for quicker retrieval.
Hardware that is located between a client and a network server. Proxy servers filter requests that enter a network and improve performance by fulfilling small requests before they are sent to the network server.
A proxy server typically sits on a network firewall and enables clients behind the firewall to access Web resources. All requests from clients go to the proxy server rather than directly to the destination server. The proxy server forwards the request to the destination server and passes the received information back to the client. The proxy server channels all Web traffic at a site through a single, secure port; this enables an organization to create a secure firewall by preventing Internet access to internal machines, while allowing Web access.
A computer intermediate between a website host computer and a user's desktop computer (such as a commercial online service computer, an ISP computer or a network relay computer) that locally stores and serves frequently requested web documents.
an intermediary between your computer and the one that you want to access. A request for a resource is directed to the proxy server which asks, gets, and forwards it to your computer.
Located between Web browser and another server;, the Proxy Server fulfils requests for information from a locally stored cache and ensures security and administrative control.
A proxy server is a server that acts as an intermediary between a computer and the Internet, and that ensures security, administrative control, and caching. Caching speeds up Internet access. If one or more Internet sites are frequently requested, they are kept in the proxy's cache, so that when a user requests them, they are delivered directly from the proxy's cache instead of from the original Internet site.
A network server that sits in between the local network and the Internet, protecting the local network from attacks as well as caching web pages to improve web surfing speed.
A server that allows users to access restricted resources from outside of a defined domain. See Connecting from home
The host server, connected to the Internet, that does something (such as take requests of a site to visit) in behalf of its users.
The proxy server allows you to sign on with your Loyola ID and access library resources from off campus.
A Proxy Server is a server that all or some of the computers on a local network have to go through before accessing information on the Internet. By using a Prozy Server you can improve the network performance, and filter what the network users can access on the internet. A proxy server can improves Internet access speeds by using a caching system. Caching saves recently viewed Websites, images, and files on a local hard drive so that they don't have to be downloaded from the internet again. The main purpose a proxy server is to filter network activities.
A server that acts as an intermediary between a workstation user and the Internet. A proxy server is associated with or part of a gateway server that separates an enterprise network from the outside. A proxy server normally contains a firewall.
Proxy servers adopt a store-and-forward approach to protecting crucial data and applications. They terminate the incoming connection from the source and initiate a second connection to the destination, insuring that the incoming user has appropriate access rights to use data requested from the destination before passing that data on to the user.
A Proxy is a shared gateway to the Internet. Proxy servers cache large volumes of Web pages and can speed up download times. You do not need to configure a proxy for connecting to BTopenworld. If you do have a proxy confugired, you connection attempt will fail. Help Home Glossary A B C D E F G H I J K L N O Q R S T U V W X Y Z Surftime The friendly name for BTopenworld for Surf Packages. Surftime allows unmetered Internet connections at specified times of day. You must register for Surftime with both BT telephony (150) and BTopenworld, the ISP.
The UCSD Proxy Server allows off-campus students to access copyrighted and/or secured resources from home, such as the Library's e-reserves. To use the proxy server you must have your UCSD username (usually your the part before the @ucsd.edu of your e-mail address) and your network password. For more information about setting up a proxy server please visit UCSD Web Proxy Server / Web Cache Page
A technique used to cache information on a Web server and acts as an intermediary between a Web client and that Web server. This is common for an ISP especially if they have a slow link to the Internet. Proxy servers are also constructs that allow direct Internet access from behind a firewall. They open a socket on the server, and allow communication via that socket to the Internet. For example, if your computer is inside a protected network, and you want to browse the Web using Netscape, you would set up a proxy server on a firewall.
In an enterprise that uses the Internet, a proxy server acts as an intermediary between a workstation user and the Internet. This provides security, administrative control, and a caching service. Any proxy server associated with a gateway server, or part of a gateway server, effectively separates the enterprise network from the outside network and the local firewall. It is the firewall server that protects the enterprise network from outside intrusion. A proxy server receives requests for Internet services (such as web page requests) from many users. If the proxy server is also a cache server, it looks in its local cache of previously downloaded web pages. If it finds the page, it is returned to the user without forwarding the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from another server over the Internet. When the requested page is returned, the proxy server forwards it to the user that originally requested it.
firewall server plus a full-featured proxy cache server that can drastically increase the intruder protection features of a corporate network. Additionally, a good proxy server can substantially increase the data throughput of any firewall system. Click here for an example of a proxy server.
server that sits between the client & the server - it may perform some of the tasks of the server itself or filter invalid requests. Reasons for this may be for security or to speed up processes
A proxy server retrieves documents on demand from a server and passes them on to a client. The advantage with a proxy server is that it normally caches documents. It is considerably faster to retrieve documents from the proxy rather than directly from a web server, especially if someone else has already retrieved that particular document.
A proxy server is a server that provides a complete company network with access to the Internet through a connection. Proxyservers also exist to store popular data, such as often-requested webpages, locally on the computer of the provider itself. As a result, access to this information will be provided a lot faster. See also cache. A proxy server can be the cause of a situation in which you still see 'old' information in your browser, although the information is already adapted on the server.
A computer that acts as a relay between remote servers and clients to intercept requests and process communications on behalf of proxy clients.
a local server that acts as an intermediary between the user and the Internet, storing web sites and increasing security
A proxy server intercepts requests destined for a particular web site. Popular pages are stored on the proxy server and these pages are served back to the user. On an Intranet/Internet landscape, a proxy can improve delivery of web pages, even serving cached versions of a page after the website itself has gone down. Another function for a proxy server is to block certain websites that you don't want your users/employees/students/citizens from seeing.
A specialized device, often made by installing proxy server software on a common PC, which acts as a LAN's representative to the larger Internet, so that Web pages or other remote resources are requested "by proxy." Proxy servers can increase network security and performance. Security is increased by placing an intermediary between sensitive internal devices and the Internet resources that they access. Performance can be increased by using the proxy server to store local copies of regularly requested information (files, data, images, etc.) Back
A server that acts as an intermediary between another computer and the Internet. The proxy server substitutes its own IP address for the IP address of the computer on the network making a request, so that all traffic over the Internet appears to be coming from only the IP address of the proxy server.
Computers, such as those belonging to Internet service providers, that act as agents for multiple users, resulting in many users only having one IP address.
A computer that stores any page that a user has already called up from the main Web site and which holds that page in store in case anyone else wants to see it. When a subsequent user requests that page, the proxy server sends the stored page out immediately, instead of asking the main site to delve into its database to deliver that page all over again. ISPs set up proxy servers, which can account for outdated content you may find on the Web.
A server that prevents direct communication between two or more networks but forwards alllowable data requests to remote servers and/or responds to data requests directly from stored remote server data.
A server that sits between a client application, such as a web browser, and a real server, containing the data to which the user requires access. It intercepts all requests to the main server. The function of the library proxy server is to allow remote web access to databases restricted by license to specific sets of users. The proxy server requires that the user provide some kind of authentication ( usually a user ID and password), before permitting access to the main server containing the restricted access files.
If you have a firewall at your site, you can't normally connect directly to a server on the Internet. You need an agent, a proxy server running on the firewall, to make the connection for you. To you, inside the firewall, it pretends to be the server that you're attempting to connect to; on the outside, it pretends to be the client, and talks to the real server, thus letting you talk to a server outside the firewall (or vice versa).
A server that relays requests and responses between clients and other servers.
Server that caches Web content in order to provide quicker access for users, when new requests are made for the same content. ublic Key A key for both encryption and decryption that is made available to the public. It has a mathematical relationship to the private key which means that information encrypted with one key can only be decrypted with the other.
Serves as a relay between two networks, breaking the connection between the two. Also typically caches Web pages.
A proxy server is a computer server which acts in the place of individual users when connecting to Web sites. The proxy server receives requests from individual workstations and PCs and then sends this request to the Internet. It then delivers the resultant information to the requesting PC on the network.
An intermediary server that accepts requests from clients and forwards them to other proxy servers, the origin server, or services.
Basically serves the same function of a router, but is a actually a program on a computer (usually a server) with a connection to a LAN and to the internet. Usually only used by corporations.
normally software which acts as a router. A user sends a request to the proxy that then sends a request to a server on the internet. For the web server accessed it is as if the proxy itself made the request, not the end user. A proxy server also helps to access web pages more efficiently. It will provide the user with web pages already requested before without requiring outside access to the internet
An Internet server that controls client computers' access to the Internet. Using a proxy server, a company can stop employees from accessing undesirable websites, improve performance by storing webpages locally, and hide the internal network's identity so monitoring is difficult for external users.
A server that acts as an intermediary between an individual user and the Internet..
An intermediary server acting on behalf of another server. It can be used so that web sites can be temporarily be stored locally on a network
An older method of Internet connection sharing. Client in a local network does not communicate directly with the target computer in the Internet but it passes its request to a proxy server. The proxy server will process the request and deliver the response.
Enables authorized users to access licensed library resources from off campus. See http://www.lib.ucdavis.edu/ul/services/connect/ for instructions and additional information.
Provides off-campus access to library databases. The proxy server provides the one password access to databases at LMU.
A server computer that controls Web-based traffic between local area networks and the Internet or other intranets.
A Web server between a Web site and a user's browser that is used to cache frequently accessed data from a Web site so that it may be accessed quicker.
a computer connected to multiple networks that serves one or more client machines. Proxy servers can connect risk a local area network to the Internet, and be part of a firewall protection system.
Server outside a company's network that controls which communications pass into the company's network, functioning as a firewall that carefully screens all incoming and outgoing messages. 12.25
Server that acts as a buffer between a number of users and the Internet. The proxy server collects users' requests, sending them on to the Internet and then serving the users. It has a buffer, the so-called cache, in which often-consulted pages are stored. The advantage of this is that similar requests are grouped, thus enhancing performance.
A proxy server is used to provide additional security between a computer and the Internet often used in conjunction with a firewall.
A relay between two networks that interrupts the physical connection between the two.
Also called a Proxy or Application Level Gateway, it is an application that breaks the connection between sender and receiver. All information a person downloads first goes to a proxy server, which immediately forwards the information. This protects the identity of the receiver.
An intermediate Web server that can be used to remove ads from web pages, or cache web pages for a local area network.
A server that proxies for the real server, or host. In OracleAS Single Sign-On, proxies are used for load balancing and as an extra layer of security. See load balancer.
A technique used in larger companies and organizations to improve network operations and security. The proxy server receives requests intended for another server to prevent direct communication between two or more networks. The proxy server forwards allowable data requests to remote servers and/or responds to data requests directly from stored remote server data. close
A server that acts as an intermediary between a user and the Internet to ensure security, administrative control, and caching service.
A server, typically on a private network, that allows access to external network resources. In a common network configuration, the computers on a company network are separated from the Internet by a firewall (for security reasons). Since these computers cannot access the Internet directly to browse web pages, the browser must be configured to use a proxy server (which is allowed to access the Internet) to service requests for web pages from the Internet. All common browsers support this configuration, usually in a configuration section titled \"Use a Proxy Server\".
A server that acts as an intermediary between a user\'s computer and the computer they want to access. If a user makes a request for a resource from computer \"A,\" this request is directed to the proxy server, which makes the request, gets the response from computer \"A,\" and then forwards the response to the client. Proxy servers are useful for accessing World Wide Web resources from inside a firewall.
A way of configuring the server that allows corporate clients to access the World Wide Web through Purveyor, without compromising corporate security. A proxy server is typically located at a "firewall" between a corporate IP network and the rest of the Internet.
A computer process that relays a protocol between client and server computer systems, by appearing to the client to be the server and appearing to the server to be the client. [RFC 2828
Typically sits between a real server and a Web browser. Its purpose is to improve performance by delivering previously stored pages. It also acts as a filter against the more ‘undesirable' material available.
An "in betweener" for the user making a request, and the host supplying the response. Proxy servers are most commonly set up on local area networks. Proxy servers can speed surfing by keeping local "cached" copies of frequently requested websites; however, these copies may be out of date on constantly updated sites.
A server external to the system used in a client-server configuration to perform processor-intensive functions, such as Natural Language Speech Recognition (NLSR) or text-to-speech. See also Proxy Text-to-Speech (PTTS).
A Web server that allows setting up of proxy services. Available from Netscape Communications, CERN, and other sources.
A server that is located between two servers, usually to increase performance or security, or both. It processes tasks rather like a phone switchboard operator does, passing them to another server if it cannot process them.
A Proxy Server sits in between a Client and the "real" Server that a Client is trying to use. Client's are sometimes configured to use a Proxy Server, usually an HTTP server. The clients makes all of it's requests from the Proxy Server, which then makes requests from the "real" server and passes the result back to the Client. Sometimes the Proxy server will store the results and give a stored result instead of making a new one (to reduce use of a Network). Proxy servers are commonly established on Local Area Networks.
A server that receives requests intended for another server and that acts on the behalf of the client behalf (as the client proxy) to obtain the requested service. A proxy server is often used when the client and the server are incompatible for direct connection. For example, the client is unable to meet the security authentication requirements of the server but should be permitted some services.
A server that sits between your browser and a web server. The proxy server intercepts all requests by your web server and checks that it doesn't have the requested web page stored on its hard disk. If it has, the proxy server returns the requested web page from its hard disk. Proxy servers help to speed up internet access and can also be used to filter out requests for unsuitable web pages.
A PC that acts as a gateway between the Internet and the local network PCs.
A server that sits between a client application, such as a Web browser, and another server. Used to filter requests—to prevent access to certain web sites, for instance.
A computer application that, among other things, allows students to access library databases from a personal Internet account.
A server that routes communication between a computer network and other computers to prevent unauthorized access to the network
A piece of software that sits between a client application (such as a Web browser) and the Internet. It intercepts all traffic flowing between the two and analyzes them This allows proxy servers to do two important things. One is to boost Internet access speeds for groups of users. Since the proxy server stores a "cache" of recently downloaded Web sites, any user that tries to access a Web site that has recently been accessed by another user is simply sent the cached version from the proxy server. The other important function is filtering. A proxy server can be set up to filter all attempts by users to access specific Web sites.
A proxy server acts as a security barrier between your internal network (intranet) and the Internet, keeping unauthorized external users from gaining access to confidential information on your internal network. This is a function that is often combined with a firewall. A proxy server is used to access Web pages by the other computers. When another computer requests a Web page, it is retrieved by the proxy server and then sent to the requesting computer. The net effect of this action is that the remote computer hosting the Web page never comes into direct contact with anything on your home network, other than the proxy server. Proxy servers can also make your Internet access work more efficiently. If you access a page on a Web site, it is cached on the proxy server. This means that the next time you go back to that page, it normally does not have to load again from the Web site. Instead it loads instantaneously from the proxy server.
Proxy servers can be used for sharing a single Internet connection among a number of workstations. It can monitor and intercept certain requests being sent, and therefore filter access to and from the Web.
Existing between a client Web browser and a real server, a computer that caches common and often requested Web pages and holds them for easier access by users. Proxy servers allow for faster access to Web pages for groups of users in a particular area. For example, quick access to popular online services such as America Online is provided by AOL's many proxy servers, which are positioned regionally.
A filter for the Internet that can be used to prevent access to Web sites containing questionable material. It connects to the Internet on your behalf, fetches pages for you, stores them locally, and delivers them to your desktop when requested to do so.
Proxies are used as intermediaries in connections to the Internet. They are generally only useful for common application uses such as web browsing. Proxies offer several benefits. They are able to cache page content locally; reducing Internet bound traffic as well as local response time. They offer some security benefits by isolating the local network from direct contact with the Internet. They also offer local ability to restrict access to the Internet in general. Proxies do have many limitations, one of which is that they cannot handle ICMP traffic. For small networks a NAT is a superior solution to a proxy.
A server that acts as a go-between, converting information from Web servers into HTML to be delivered to a client computer. It also provides a way to deliver network services to computers on a secure subnet without those computers needing to have direct access to the World Wide Web.
Also called a proxy, it is a computer system or router that breaks the connection between sender and receiver. Functioning as a relay between client and server, proxy servers are used to help prevent an attacker from invading the private network. Proxies are one of several tools used to build a firewall. Open
A server that provides access to files from other servers by retrieving them either from its local cache or from the remote server.
A proxy server sits in between a client and the "real" cerver that a client is trying to use. Client's may be configured to use a proxy server; usually an HTTP server. The clients makes all of it's requests from the Proxy Server; which then makes requests from the "real" server and passes the result back to the Client. Proxy servers can cache results and give the stored result instead of making a new one. Proxy servers are commonly used on LANs
A server that substitutes for the real server, forwarding client connection requests to the real server or to other proxy servers. Proxy servers provide access control, data and system security, monitoring, and caching.
Sits in between the client and the Real server that a client is trying to use. Client's are sometimes configured to use a proxy server usually as an HTTP server. The client makes all its requests form the proxy server which then makes a request form the real server and passes the result back to the client. Commonly established on LAN.
Sites between a client, such as a Web browser and a real server. They're more often used to improve performance by delivering stored pages like browser cache and to filter out undesirable material.
A computer used to store copies of popular webpages at an ISP and provide them on request, to save having to fetch them from the website each time.
'Proxy' means something like 'representative service': Proxies accept the requirements of a client (e.g. a WWW browser) and forward them, modified if necessary, to the original target (e.g. a WWW site). A proxy can store the passed data locally and deliver it directly the next time it is accessed.
A proxy server is one that acts on behalf of one or more other servers, usually for screening, firewall, caching, or a combination of these purposes. Gateway is often used as a synonym for "proxy server." Typically, a proxy server is used within a company or enterprise to gather all Internet requests, forward them out to Internet servers, and then receive the responses and in turn forward them to the original requestor within the company.
A server resides between the workstation and the Web server. The proxy server is part of the network that protects the organization from unauthorized access. It helps filter requests and provide security.
a server that sits between a client application (your computer) and a real server. The library's proxy server controls access to remote Web servers, providing access to the library's subscription databases to valid patrons anywhere in the world. (See OFF-CAMPUS ACCESS)
A special server that acts as an intermediary between a client and the server that the client really wants to connect to. Proxy servers are used on networks where most computers are not permitted to make Internet connections; instead those computers must connect to the proxy, which in turn connects to the desired server. Fetch supports a number of proxy servers (see the Proxy Preferences topic). Web proxy servers, which use the HTTP protocol rather than FTP, are not supported.
A firewall component that manages Internet traffic to and from a local area network (LAN) and can provide other functions, such as document caching and access control.
A proxy is used on a gateway that relays packets between a trusted client and an untrusted host. A proxy server is software that runs on a PC and is basically a corporate telephone system for the Internet.
A proxy server stores copies of web pages that you access so that they can be brought up more quickly when you want to access them again. When you ask for a web page, the proxy server checks to see if the web page is stored in its cache. If it is, it returns that copy, without having to access the Internet. The proxy server may be located with the Internet Service Provider that you dial in to, or it may be located on your own server. Proxies do speed up access considerably, but depending on how the proxy server is configured, they may sometimes bring up stored older versions of websites, without showing changes made in the last few hours.

server between a client application, such as a Web browser, and a real server. It intercepts all requests to the real server to see if it can fulfil the requests itself. If not, it forwards the request to the real server. Proxy servers have two main purposes: improve performance and filter requests.
An intermediary program that acts as both a server and a client for the purpose of making requests on behalf of other clients. Requests are serviced internally or by passing them on, possibly after translation, to other servers. A proxy interprets and, if necessary, rewrites a request message before forwarding it.
Derived from legal terminology, a server that acts as a proxy on behalf of a client. Proxy servers are frequently used as intermediaries between LANs and the Internet. They perform a variety of tasks, caching previously loaded pages to speed up access, incorporating NAT and/or firewall functionality, and more.
Also termed ‘proxy' or ‘application level gateway', it is an application that breaks the connection between the sender and the receiver. All input is forwarded out on a different port, closing a straight path between two networks and preventing a cracker from obtaining internal addresses and details of a private network. Proxy servers are available for common Internet services, e.g. an HTTP proxy is used for web access and an SMTP proxy is used for email. Proxies generally employ network address translation (NAT), which presents one organisation-wide IP address to the Internet. It funnels all user requests to the Internet and fans responses back out to the appropriate users. Proxies can also cache web pages, so that the next request can be obtained locally.
A proxy server is a process that acts like a switchboard through a firewall to manage the various types of permitted communications with the outside world. Proxy servers may also use caching to make communications more efficient.
A proxy is an intermediary between a web server and a computer. It's used to cache (store) information, like frequently used web pages
In general, a proxy server is a program that receives a URL from a browser, retrieves the data specified in the URL from a server, performs a service on the data, and serves the resulting data to the requesting browser. In the case of the VM:Webgateway proxy server, it receives a URL from a browser, communicates with IpServer running on a VSE system to retrieve data from the CICS application specified in the URL, and sends the data to the requesting browser.
An internet server that allows several users to share one internet connection, reducing the number of IP addresses required. Users are assigned IP Addresses from a limited range, as and when they are required.
A program that deals with external servers on behalf of internal clients. Proxy clients talk to proxy servers, which relay approved client requests to real servers, and relay answers back to clients.
A server that can retrieve documents from other servers for its clients.
Also known as cache server, it is used by Internet Service Providers to hold cached Web pages.
A server that sits between a client and a web server and represents itself to each end as being the other. It can be used in two ways. For the web server it can cache frequently accessed pages to reduce the web-server's traffic. For security of the LAN clients it can present a single IP address to the Internet and prevent direct access to the rest of the LAN.
A computer that controls traffic between a Local Area Network and the wider Internet. Hunter Library at Western Carolina University requires that you configure your browser to communicate with their proxy server for accessing library resources. Instructions on how to do this can be found here.
A computer which stores a copy of the most frequently downloaded web sites, in order to give faster access to these pages.
An internet server that acts as a firewall, mediating traffic between a protected network and the Internet.
A proxy server is a computer that is in between your computer and the Internet. Your computer sends requests to the proxy server, which sends them on to the Internet. Replies come back to the proxy server, which relays them on to you. The proxy server can examine the requests and block any that it determines to be inappropriate.
A proxy server is a server located on a network between client software, such as a web browser, and another server. It intercepts all requests to the server to determine whether it can fulfill them itself.
A computer that will function on behalf of another. Often used as a method to anonymously attack others on the Internet.
Software that runs on a firewall host and transmits information (usually from certain applications or types of applications) past the firewall in both directions. It's a server because it responds to requests from clients, and it's a proxy because it acts in place of the external server that the client is actually trying to reach.
A server that sits between a client application, such as a browser that sends HTTP requests, and a web server. A proxy server intercepts each request to the web server to see if it can fulfill the requests itself. If not, it forwards the request to the web server. A proxy server can also filter requests that are sent to the web server, to restrict access or improve performance. The CyberSource ICS server supports SCMP messaging to and from your proxy server.
A server that provides information accessed from other servers.
a combination of software and hardware, which acts as an intermediary between a set of users and the Internet, allowing authorized users to access many electronic resources available through the UNC library web pages from home.
An intermediate device that receives SIP requests from a client and then initiates requests on the client's behalf.
A system that caches items from other servers to speed up access. On the Web, a proxy first attempts to find data locally, and if it's not there, fetches it from the remote server where the data resides permanently.
An indirect means of connecting to the Internet. A desktop connects to a server, which then connects to the Internet. Sometimes this is done to filter content or intercept viruses before they infect an internal network. If you are connecting to the Internet via a proxy server, you will need to make some changes in your RSS reader configuration.
A server that provides firewall functionality, acting as an intermediary for user requests, establishing a connection to the requested resource either at the application layer or at the session or transport layer.
A proxy server acts as an intermediary between a computer and the Internet so that a network of computers set up behind the proxy server can ensure security, administrative control, and caching service. The network is separated from any direct outside connections. To the user, the proxy server is invisible; all Internet requests and returned responses appear to be coming directly from the addressed Internet server even though they pass through the proxy server first.
A server located on a network between client software, such as a Web browser, and another server. It intercepts all requests to the server to determine whether it can fulfill them itself. If not, it forwards the request to another server.
A server that sits between a client application (such as a browser) and a "real" server. The proxy server intercepts client requests and forwards them to the other server. Its purpose is two-fold: for outgoing traffic, it allows private, non-routable machines to reach a machine which can reach the Internet for them. Secondly, as it receives responses to the client machine requests (for example, Web pages) it can cache them locally so that further client requests can be answered locally and immediately.
A proxy server acts as an intermediary between your internal network (intranet) and the Internet, retrieving files from remote Web servers.
A network component between a LAN and the Internet providing security, administrative control and data caching. It is also a firewall that protects the network from intrusion.
A server that sits between a client application, such as a Web browser, and a real server. It intercepts all requests to the real server to see if it can fulfill the requests itself.
An Internet server that acts as a firewall, mediating traffic between a protected network andthe Internet. Hosting
A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache.
