Soon her eye fell on a little glass box that was lying under the table: she opened it, and found in it a very small cake, on which the words "EAT ME" were beautifully marked in currants. "Well, I'll eat it," said Alice, "and if it makes me grow larger, I can reach the key; and if it makes me grow smaller, I can creep under the door: so either way I'll get into the garden, and I don't care which happens!"

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.
