http proxy to bypass school firewalls

i've lost my source code to create a proxy to bypass my little brothers scho
ol firewall.
i cant find it. i was just going to insert the code into the web edit on my 
website on BRAVENET.
can somebody provide a code.  i dont want the file, i dont understand them, 
just the code, or a cgi proxy source code or something to get past blocked s
ites.
