I remember having a problem back in the RH (not RHEL) 5 or 6 era where
I was using ProxyPass or rewriterules with [P} and it somehow enabled
random proxy requests which I noticed when the logs filled up with
requests that were intended to run up to run up some other sites ad
counters.  It is too far back to remember if that was the default from
the install or was related to what I did to enable the specific proxy
functions I needed, though.
