Interesting - so the meta question is this - how do browsers decide what
to provide to servers? Do they do any negotiation and decide to speak
one or the other? I'm not asking because I want to read the HTTP spec -
but in layman's terms - how do browsers and servers decide what to speak
to each other? Can a server speak either/or/both for the same domain?
