while setting up apache as an ssl proxy to some backend servers I noticed that a reverse lookup is performed for each new connection to the internal server.
I wondered if it was possible to prevent this but by looking at the source code of mod_proxy it doesn't seem so.
As a workaround I've added the internal server's ip addresses to /etc/hosts.
IMHO the reverse lookup should be made avoidable from the configuration file. (Maybe it should be made avoidable completely, unless I'm missing a possible reason to revese lookup there...)
