What is a proxy server? During a HTTP connection, the IP address of the client machine is necessarily transmitted in order to get the information back. This allows a server to identify the source of the web request. Any resource you access can gather personal information about you through your unique IP address - your ID in the Internet. They can monitor your reading interests, spy upon you and log your requests for third parties. Also, owners of the Internet resources may impose some restrictions on users from certain countries or geographical regions. An anonymous proxy server acts as a middleman between your browser and an end server. Instead of contacting the end server directly to get a web page, the browser contacts the proxy server, which forwards the request on to the end server. When the end server replies, the proxy server sends the reply to the browser. No direct communication occurs between the client and the destination server, therefore it appears as if the HTTP request originated from the intermediate server. The only way to trace the connection to the originating client would be to access the logs on the proxy server (if it keeps any). So an anonymous proxy server can protect your identity by stripping a request of all identifying information. A middleman between your browser and an end server. Pic 2. A middleman between your browser and an end server. Another common use of anonymous proxies is to access sites which are normally blocked by your upstream ISP. For instance, proxies are often used by people to access sites which have been censored by their companies, organizations or governments. A web proxy is a type of proxy server that works through a web form. Instead of configuring the address of the server in the browser as is done for HTTP or SOCKS proxies, you simply navigate to the home page of the web proxy. Web proxies hide users identity from the sites they visit, keep cookies at their site, and delete them after each session and selectively remove scripts, images, etc. To use a web proxy all you have to do is to visit its home page, enter a web address in a small form and hit Go. It makes all of your requests on your behalf, so the website you are viewing only sees the IP address and information of the web proxy, not yours. Web proxies support HTTP and sometimes HTTPS and FTP protocols. There are many proxies available, some are free, some require a low monthly or one-time fee for use, and some are for private groups or parties.
