A proxy is something that does something in place of something else. When it comes to websites, a proxy is a site or program that you use that connects to sites on your behalf. There are various different types and reasons for using such a program or website.

One implementation is a VPN. That is a website that you subscribe to that will go to other websites for you. A company may use such a site to protect themselves from certain types of hacking and snooping. So if someone tries to get in, they end up hacking into the VPN, not the company's site.

There is also the possibility of getting around firewalls. A firewall is a program or set of rules that prevents certain types of network traffic or prevents access to certain types of sites. Schools and workplaces often use them, but so do nations ran by fearful (and fearsome) dictators and governments. Some users will use proxies to get around firewalls. However, WikiAnswers does not provide the details on how to actually do so.

An anonymous proxy server hides an IP address by making requests for data on another computer's behalf. If you are browsing the web through an anonymous proxy server, your computer tells the proxy server what website you want to view. The proxy then connects to the website for you. The website uses the IP adddress of the proxy server to send back the requested data. The proxy server then sends the data you requested (the website) back to you. Not all proxy servers are anonymous. Also, for the anonymous proxy server to work as intended, it needs to be configured properly.
