Web proxies and anonymous surfing


In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client.

A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it would 'cache' the first request to the remote server, so it could save the information for later, and make everything as fast as possible.

A proxy server that passes all requests and replies unmodified is usually called a gateway or sometimes tunneling proxy.

At schools and offices Many work places and schools are cracking down on the web sites and online services that are made available in their buildings. Since circumventors are used to bypass censors in computers, web sites like MySpace, Bebo, Xanga, Silkroad Online, YouTube, Miniclip, Facebook, and other non-work or school related social web sites have become targets of mass banning.

Proxy Web server creators have become more clever allowing users to encrypt links, and any data going to and from other web servers. This allows users to access websites that would otherwise have been blocked.

A special case of web proxies are "CGI proxies". These are web sites that allow a user to access a site through them. They generally use PHP or CGI to implement the proxying functionality. CGI proxies are frequently used to gain access to web sites blocked by corporate or school proxies. Since they also hide the user's own IP address from the web sites they access through the proxy, they are sometimes also used to gain a degree of anonymity, called "Proxy Avoidance".
