Discovering HTTP #1: The Accept header (Loud Thinking)
Oooh! From reading the comments, this looks like an instant headache. I was thinking of using content negotiation to decide on whether my blog’s frontpage should return (X)HTML, Atom, or RSS. I think before I do that I’ll track what Accept headers are sent by aggregators subscribed to my feeds right now and make a descision later as to whether this is feasable.
