Reverse proxy - a proxy server, which in contrast to the direct relays client requests from the external network to one or more servers that are logically located on the internal network. Often used for network load balancing across multiple web servers and increase their safety, playing the role of a firewall at the application level.

For the purpose of anonymization used Web proxy. Web Proxy - a proxy server and anonymizing special form, which is a web application (mostly PHP or Perl script) is installed on the web server, acting as a mediator to download the content of various Web sites.

Administrative methods to counteract the use in local area networks web proxy may be: increased content filtering and blocking addresses public Web proxies. It should be noted that most hosters Do not install on cheap fares shared hosting web proxy due to the high server load and active consumption of incoming traffic. Despite this limitation, the Internet is widespread creation of entire networks from a Web proxy, they represent a large number of different domain names hosted on one or more IP-addresses of dedicated servers. These networks are used by their owners to profit from advertising placed on these resources.
