When are Web proxy servers useful?
CGI proxies (web proxies) are web sites which allow a user to access other sites through them. A user visits a CGI proxy web site and then requests a web page, a file or other resources available on other sites. Web proxy sends this request to the necessary site, gets “answer” and returns it to user. A Web proxy allows a user to be anonymous and access web sites that may be restricted for users from certain countries or geographical regions. Web proxies are frequently used to gain access to web sites blocked by corporate or school proxies. As well as hiding user’s IP address and providing a way to access blocked web sites, a Web proxy can also block scripts, cookies, images, etc.
