I could however configure another virtual host with authentication, pointing to the (non-troublesome) backend. >> I'm currently running CentOS 5 with Apache 2.2.3 (including all the >> patches that RedHat have backported). > > FWIW, there are a lot of proxy improvements since 2.2.3. > That includes a patch to PR#37770, which could be relevant. Just had a speed-read of that one, although there's lots of mention of the problem occurring with the worker mpm. FWIW we're using prefork mpm as there's a lot of PHP code being served.
