Proxy Servers

What is a proxy server?
A proxy server is a kind of buffer between your computer and the Internet resources you are accessing. The data you request come to the proxy first, and only then it transmits the data to you.

What is an anonymous proxy server?
Anonymous proxy servers hide your IP address and thereby prevent unauthorized access to your computer through the Internet. They do not provide anyone with your IP address and effectively hide any information about you and your reading interests. Besides that, they don’t even let anyone know that you are surfing through a proxy server. Anonymous proxy servers can be used for all kinds of Web-services, such as Web-Mail (MSN Hot Mail, Yahoo mail), web-chat rooms, FTP archives, etc.

Why do I need to use proxy servers?
1. Transfer speed improvement. Proxy servers accumulate and save files that are most often requested by thousands of Internet users in a special database, called “cache”. Therefore, proxy servers are able to increase the speed of your connection to the Internet. The cache of a proxy server may already contain information you need by the time of your request, making it possible for the proxy to deliver it immediately.

2. Security and privacy. Anonymous proxy servers that hide your IP address thereby saving you from vulnerabilities concerned with it.

3. Sometimes you may encounter problems while accessing to web server when server administrator restricted access from your IP or even from wide IP range (for example restricting access from certain countries or geographical regions). So you try to access those pages using an anonymous proxy server.

What is a public proxy server?
It is a proxy server which is free and open for everybody on the Internet. Unfortunately most of them are not anonymous.

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 web 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 serves as a middleman between your web browser and an end server. Instead of contacting the end server directly to get a Web page, the browser contacts the proxy, which forwards the request on to the end server. When the end server replies to the proxy, the proxy sends the reply on 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 proxy server. The only way to trace the connection to the originating client would be to access the logs on the anonymous web proxy (if it keeps any). So an anonymous proxy server can protect your identity by stripping a request of all identifying information.

Another common use of anonymous proxies is to access sites which are normally blocked by your upstream ISP. For instance, web proxies are often used by people to access sites which have been censored by their companies, organizations or governments.

An anonymous web proxy is a type of proxy server that works through a web form (also often called a CGI proxy). 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 / CGI 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 web form and hit «Go». A proxy makes all of your requests on your behalf, so the web site you are viewing only sees the IP address and information for the proxy server, not yours. Web proxies support HTTP and sometimes HTTPS and FTP protocols. There are many web proxies available, some are free, some require a low monthly or one-time fee for use, and some are for private groups or parties
