How does my school's proxy work ? (Really abnormal and tough!)?

All your school computers are linked in an intranet network, which in turn can connect to the web.Your systems administrator has configured your system such that all outbound traffic goes through a proxy,so when you use a web browser a request is sent from your pc to the proxy, the proxy checks your request against a list of known forbidden sites and phrases e.g facebook may be forbidden, in which case when you try to access facebook, the proxy which all your outbound traffic has to go through simply rejects your request. The proxy also detects key words e.g '****' or porn which will most likely be blocked too. All websites identify themselves as either gaming sites, interaction sites, file sharing etc, if you try to access any of these The connection is refused.To complicate matters further the proxy is made to recognize proxy sites and even has a database of known proxy servers and sites, which are also blocked/banned.There is virtually no way of accesing external sites(not on your school network) without going through their proxy Computer-Intranet-Proxy-Internet, thats how it works, Your only hope of bypassing this is a proxy site which isnt on the list of known proxies,and doesnt set of any alarms by having key words such as 'proxy' etc.I cannot really tell you HOW to bypass it as proxies vary
