Proxy Sites
A Proxy site is a web page which allows you to browse your favorite web sites — even though your access to those web sites might be blocked by a content filter, such as WebSense or SmartFilter. The proxy site also helps to mask the visit to the site, so that there is less evidence that the content filter was not successful in preventing the visit. They enable you to bypass your own internet provider and browse anonymously.
Unblock Websites
A website can be blocked by a number of programs, particularly security software. These programs work with Web browsers, which allow users to view the World Wide Web. Some Web browsers even come with their own filters to restrict access to websites with certain content. System administrators of a LAN (Local Access Network) can also block access to websites on the network level.
