How a proxy unblock sites!

Computers/Internet March 10th, 2010

Many people are using proxy sites for unblocking sites like myspace, facebook, orkut, etc. A free proxy can be used for unblocking your favorite sites. How a proxy can unblock such sites is still a mystery to many of the people who use proxies. There are two ways in which a proxy site unblock your favorite sites from your network filter. They are:

1. Proxy IP address: A proxy server hides the ip address of the web server from the network of the end user. To the user’s network, the end user seems to be browsing the proxy site and not the website which is browsed through the proxy. So, if you are browsing facebook through a proxy, your network filter can’t detect that you are browsing facebook.
2. Url Proxy: A proxy site proxies the name of the domain that the user is browsing. Many of the website blockers block sites based on the domain of the website or the url of the site. When you are browsing through a proxy, the url is that of the proxy and not that of the website you are browsing.
So, when you browse through a proxy, the proxies hide ip address of the destination server and hides the url thereby rendering the network filters undetectable.
