Proxy Servers
A proxy server is a kind of buffer between your computer and the Internet resources you are accessing. They 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. The overall increase in performance may be very high. Also, proxy servers can help in cases when some owners of the Internet resources impose some restrictions on users from certain countries or geographical regions. In addition to that, among proxy servers there are so called anonymous proxy servers that hide your IP address thereby saving you from vulnerabilities concerned with it.
Transparent Proxy IP address can be caught by sever using HTTP_X_FORWARDED_FOR variable, such proxies usually used to increase internet speed and decrease amount of abroad traffic (some internet providers grant their user free local traffic).
Anonymous Proxy IP address can not be caught by server but server knows that proxy was used during connection. It is very useful to be anonymous surfing in internet .
Elite Proxy IP address as well as fact that proxy was used during connection can not be caught by server. Best way to hide any information about you presence in internet.
Why Should You Use Anonymous Proxy Servers?
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, according to some policies of the Internet resources, deny accessing any information you might need.
You might become a target for many marketers and advertising agencies who, having information about your interests and knowing your IP address as well as your e-mail, will be able to send you regularly their spam and junk e-mails.
A web site can automatically exploit security holes in your system using not-very-complex, ready-made, free hacking programs. Some of such programs may just hang your machine, making you reboot it, but other, more powerful ones, can get access to the content of your hard drive or RAM. Everything a web site may need for that is only your IP address and some information about your operating system.
Using an anonymous proxy server you don't give anybody any chance to find out your IP address and any information about you and use them in their own interests.
