HTTP proxy bypassing techniques disclosed

Today the division got non-anonymous hints about HTTP proxy bypassing:

• "cached"-mark requests not inspected again - mmhh... ??? (maybe a flaw in a prehistoric SQUID-based HTTP proxy)
  
• TOR support built in in Firefox: nope... but there are 3 extensions, actually only 2
• SSH-based tunnel (yeah, not really new)
  
• extra-install-tools (for all those who think squid is something you can eat, tor is the reverse of rot and SSH is the secret service of Elbonia)

The division will check it and let you now.

(If you have some secret information about HTTP proxy bypassing: let us (geheimp@mailservice from google) know, we are the right division for it.
