When referring to web sites, includes allow you to use the same piece of code ( HTML, ASP, ColdFusion, etc.) over and over. For instance, if you wanted your phone number to appear on the bottom of every page on your website, you could create an HTML page that had that information. Then you could include that file in every page on your website. If your phone number changed, you would only need to modify the include file.

Includes, or SSI, are used to insert the contents of one file into another and can be used to generate dynamic web pages.

'Includes' refer to an element of code.
