In another moment down went Alice after it, never once considering how in the world she was to get out again. The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping herself before she found herself falling down a very deep well.

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.
