Proxy Sites allow you to browse the web freely at work or school, even if there is a content blocking system on your computer. The Proxy will help you covertly visit other websites by sending you through their web servers first. Content filtering systems, such as SmartFilter or WebSense, can not detect this websites visited from the proxy server, so there is no way for them to block you from viewing any website. Not only that, but the Proxy Site will also help hide the fact that the content filter failed in blocking your website, so it is less likely that it will block the proxy site in the future.
A proxy site will allow you to bypass your own Internet server and connect through the proxy server instead. This way, it does not matter what you are browsing through at work or school because it is all hidden behind the brick wall of the proxy site. There is a rather simple way proxy sites accomplish this feat. They simply open the website you wish to visit in their own window, so it appears you are just visiting the proxy website, when really you could be on any other website on the Internet.
Contrary to some popular belief websites are not blocked at schools or places of work through the browser. The network administrator blocks websites on the entire server so no one can visit them. Although some web browsers do come with the ability to block certain websites, this is not how businesses and schools choose to block content from the people using their computers. This is because users could easily just turn off the browser content filter and they can control a much larger amount of computers at one time through the network content filter.
Proxy sites are actually a decent source of income for those who create them. It will cost some money up front to start the website, but once it gets up and running, the money can be made back rather quickly by putting ads on the website, and even putting ads on top of every website visitors view from inside your proxy server. All you have to do is let people who work on computers with content filters know about your proxy server, and the visitors to your proxy site will do the advertising for you through word of mouth.
