Visitors is a 2003 movie dealing with the experiences of a woman sailing solo on a yacht around the world. The movie was directed by Richard Franklin, produced by his (now) wife Jennifer Hadden and stars Radha Mitchell in the lead role, Susannah York as Georgia's mother Carolyn, and Dominic Purcell as Georgia's boyfriend Luke.
The Visitors is the name given to a fictional alien race from the miniseries V and the TV series derived from it. These "Visitors" are reptilian humanoids who disguise themselves to look human, and prefer to eat live prey. They claimed to be from the fourth planet orbitting Sirius, but as with all their other claims, this may simply be a deception.
Visitors processes a Web log file, trying very hard to identify a single "person" as much as possible. This is typically achieved by the use of either an identifying cookie in the log file, or via the IP address, name, and browser ID combination.
Visitors is a minimalistic HTTP server log analysis program written in C. It does not require any configuration or write access to the filesystem. Visitors can produce output in plain text or HTML format and also creates Graphviz dot files showing popular paths between pages on a site.
Visitors are measured as more then one hit from a particular IP address, so long as the gap between subsequent hits is not more than 30 minutes. Visitors is a better measurements than hits because it can distinguish users reasonably well using the IP address. But hits coming from the same IP address after an idle time of 30 minutes would be considered as another visitor.
A visitor or a unique visitor is someone who visits your web site. If the visitor goes to another page however, another visitor is not counted. So the difference between a hit and a visitor is a hit is everytime your page is loaded, but a hit is everytime a computer visitors your site.
