Unusual firewall bypassing techniques, network and computer security.

There were doors all round the hall, but they were all locked; and when Alice had been all the way down one side and up the other, trying every door, she walked sadly down the middle, wondering how she was ever to get out again.

Cooking channels - is a set of two python scripts (CGI and client) allowing to build a communication channel over HTTP cookies.

The paper How to cook a covert channel [Hakin9 Pdf] originally released in the hakin9 magazine describes step by step how to implement a few covert channel concepts over HTTP cookies :
   o Control communication channel
   o As stealth as possible (don't care about latency or bandwith)
   o Backdoor oriented

The paper finally describes a funny second level caching method allowing to use HTTP proxy servers as intermediaries to build a communication channel thus having a way to communicate with a third party without having to reach the remote server for each data packet.
