The nsIHTTPInstance class is the interface to an intance
of the HTTP that acts on a per URL basis.
There are a ton of things that an instance should hold
but due to the lack of time I am letting those things
be used from the old code base. Someday someone will
step in and get rid of old code and put things here
like socket, other connection data, etc.

I am not describing each since most are obvious and then

For most of these headers there is a default that gets
set in a default HTTP request which can be modified from the
nsIHTTPHandler.
This is definitely not the complete set. But nsIHTTPRequest will
have it. TODO...
