What is Facebook tracking for God's sake?

Question for Phunk. You mentioned that http had no mechanism for a server to request cookie data. Isn't http just a protocol and html the code? Ie, the protocol is the transport mechanism and html the code that executes operations. So http would have no need to request data and would only need to favilitate the transfer of the requested data?

Yes, http is a transfer protocol, and html is often the data being transferred. But cookies are not part of html, they are part of the request and response headers in http. They work just fine with no html involved at all (http can transfer any file type, the obvious example being images).
