Hmm, but how do we Extend it?
Extensibility wasnt part of the basic 1.1 package
Work going on in HTTP Extension Group
HTTP is not a centrally controlled protocol
Has maybe never been
Being extended by everybody for any possible purpose
No structured way of extending HTTP
Extend and hope for the best!
No explicit type information
Layering is implicit - looks and feels like hairball
Using POST as a tunnel mechanism
