Point taken.

mod_proxy does the whole nine yards - it creates a real connection, then
creates requests off that connection using the same core methods you
tried. You're unlikely to find any shortcuts or ways of creating lean
requests here. :(

I am starting to think this is probably the only practical way of doing
this, unless we can come up with a dummy request_req creator that leaves
the non essential (for this case) fields as NULL.

What may be useful is to teach httpd how to handle the case where the
connection is missing, and have it fail gracefully/intelligently in this
case, however this is a big job that is likely to slow you down from
getting the first releas out the door.
