Recently I have researched on bypassing internet filters. Mainly bess and websense because their products are employed at my high school and local library. The first and easiest way to bypass the filters is to simply use a proxy that you find in any proxy list across the internet in your internet options in your browser. These proxy lists can be found with a simple google search for "proxy lists".

The most common way to bypass the filters is with some sort of web proxy. The one I use is ran by *Removed* and is scripted in php. The web proxies do the same thing as the IP proxies except they display the information requested with a programming language rather than just your browser. Web proxies are scripts that can be set up on a web server. If you have a web server that you would like to run a script on, I would reccomend *Removed*.

I would reccomend the second method because most web proxies are kept under password protection so they arent blocked quickly. The IP proxies tend to be slow and die quickly.
Hope this is helpful,

Note:

We do not in anyway support the bypassing of Internet Filters. Whilst they do block access to sites (some useful ones mind you, which can usually be unblocked by request) they also block access to potentially dangerous items on the web, such as hackers etc.

Usually, school proxy servers are set in a way that they won't allow another proxy server to be used, and usually have webcaches to, so you never actually connect directly anyway.

Well with Trilogy Group Web Proxy there can't be a cache in the schools proxy because they are password protected. The proxy chaining works well on networks that run Websense because it is usually only set to filter port 80. If users select a proxy on any port other than 80 they are most likely going to get unrestricted access. I dont agree with kids looking up **** and hate material at school, but there are authentic times when it is just necessary to have a way around the filter. I was motovated to start my investigation because my research on corruption in the Bush Administration was blocked as "hate content". It is proven that the automated-categorization that the filters use isn't always right. In fact about 30% of the pages that are blocked on free web hosts aren't inappropriate at all.

Yeah most do only block 80. However, you usually need to get admin rights on the PC first to change the proxy. As i said, if there is a legitimate reason for you to need access to a site, talk to the computer administrator, who may give you access (onces they've checked it of course).

What do you mean by there can't be a cache because there password protected???

Usually you'll have your router connected to the firewall/proxy, which is then connected to a webcache, so if you access a site, the person next to you gets it off the proxy, thus saving bandwidth!

*EDIT* - Its ok, just read your original post once yu put the URL back in!!!! No you could still have a webcache, its just the content it is getting would be from the webproxy which may or maynot be bypassing it!

Also, whilst this topic is interesting, we don't want to supply direct links or names to these programs, since bypassing them can do quite abit of damage to the school systems, as well as the security!!!
