  *) mod_mem_cache: Don't cache incomplete responses when the client aborts

                    the connection, unless they are complete.  PR 45049.

     Not applicable to trunk, mod_mem_cache doesn't exist there.

     2.2.x patch: http://home.apache.org/~ylavic/patches/httpd-2.2.x-mod_mem_cache-pr45049.patch

     +1: ylavic, wrowe, rpluem

     ylavic: don't we know from the very beginning of store_body() if

             r->connection->aborted, so to fail there?

     rpluem: Agreed. I guess we can move this up to line 733 before the loop.

     ylavic: Or even at the beginning if we want to avoid file caching too.

             But finally I wonder why we would not cache the response provided

             it is complete. Shouldn't incomplete response be detected with

             error buckets instead? ISTM that EOS with no error bucket *is*

             a complete response that could be cached even if the current

             client won't receive it completely.

     wrowe:  Patch looks like an improvement, would be good if you both assert

             that this is what we will ship.

     ylavic: This is a bugfix (added CHANGES entry), the improvement is upon

             Ed's original patch (don't cache the response if the client

             aborted the connection) where we now still cache it in any case

             if it is complete (for immediate availability for next clients).
