This was proposed for -trunk; but it would be useful for 2.2
as well...

But ap_proxy_pre_request() would need adjustment... which
is also an "exported" function...

Of course, I don't see how this could impact anyone external
since the very fact that they are RUN_FIRST and HOOK_FIRST
implies no one else is (able to) use them right now...
So yes, even though would change the public API of these
2 hooks, I think the usefulness of it is worth it, and
hence why I wanted comments :)
