When using a computer in a restricted environment like for example school, it's becoming increasingly usual to be behind a web filter. Of course they are necessary to restrict what types of contents are viewed but sometimes the web filter blocks something that's far from "bad content".
Now, this is going to be a series of posts to show you how to bypass this web filters. Each post in the series will have a different method. Of course this is only for educational purposes and I don't encourage nor discourage the use of this information.
The first method in this series if very simple. A lot of web filters have a database based on the URL of the websites. If the URL is on the database the web filter denies the access. Now, what would happen if we changed the URL of the website? That's where web proxies come in hand.
A web proxy let's you surf the web by using an online form. Just type the URL and start surfing. The difference is that the content is going to be retrieved by the web proxy and then displayed to you. This let's you surf any website if the proxy's website is not blocked of course.
To find a free web proxy just google for it and you will find one immediately. If your web filter blocks the access to all of them (which I think is unlikely), you could set up one in your home computer and access it from anywhere. This is going to be in another post of the series.
One web proxy that I use and have never seen it blocked is http://www.the-cloak.com. It's very easy to use and you will get to the websites you want without restrictions.
Thank you for reading and keep visiting to learn other methods in this series and a lot of other interesting stuff.
