what's a proxy server?

[vipeness]

A proxy server is a computer on the local network (e.g. UQconnect, or your local ISP) which accesses the Internet on the user's behalf. Most ISPs provide proxy servers for all internet protocols (ie. ftp, http) A WWW proxy server retrieves web pages on behalf of a user and then passes them onto that user. This allows faster access to frequently requested pages stored in the network proxy cache, rather than accessing the remote site every time.



A server between a client application, such as a Web browser, and a real server. It intercepts all requests to the real server to see if it can fulfil the requests itself. If not, it forwards the request to the real server. Proxy servers have two main purposes: improve performance and filter requests.



A server that acts as an intermediary between a user's computer and the computer they want to access. If a user makes a request for a resource from computer "A," this request is directed to the proxy server, which makes the request, gets the response from computer "A," and then forwards the response to the client. Proxy servers are useful for accessing World Wide Web resources from inside a firewall.



A technique used to cache information on a Web server and acts as an intermediary between a Web client and that Web server. This is common for an ISP especially if they have a slow link to the Internet. Proxy servers are also constructs that allow direct Internet access from behind a firewall. They open a socket on the server, and allow communication via that socket to the Internet. For example, if your computer is inside a protected network, and you want to browse the Web using Netscape, you would set up a proxy server on a firewall.
