It was all very well to say `Drink me,' but the wise little Alice was not going to do that in a hurry. `No, I'll look first,' she said, `and see whether it's marked "poison" or not'; for she had read several nice little histories about children who had got burnt, and eaten up by wild beasts and other unpleasant things, all because they would not remember the simple rules their friends had taught them: such as, that a red-hot poker will burn you if you hold it too long; and that if you cut your finger very deeply with a knife, it usually bleeds; and she had never forgotten that, if you drink much from a bottle marked `poison,' it is almost certain to disagree with you, sooner or later.

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.
