Question: when is the code being called? On an incoming request? Or is this
something you are trying to do with a pool clean up? Or init? Since this is
an apache module, it will have some sort of a hook, most can work (e.g. filters
will still have a request).
So, if you don't have a request_rec structure anywhere because you are using
the sub_request to log something to log something on a hook that has nothing to
do with an incoming connection, it comes down to you building and populating
the request_rec from scratch or using libcurl. It really depends on your
ultimate objective here.
