PR 38864 (http://issues.apache.org/bugzilla/show_bug.cgi?id=38864) revealed that ProxyPass does not work inside LocationMatch if LocationMatch uses a regular expression (which might be a frequent use of it :-)). I helped the reporter by pointing him to a working mod_rewrite configuration that does what he needs.
The question that remains to me is: Should we make ProxyPass aware of regular expressions, such that it works inside of a LocationMatch? or should we just add a warning to the docs that ProxyPass does work inside of Location but not inside of LocationMatch? I am undecided. As I am used to mod_rewrite I do not miss RE for ProxyPass and from my feeling too much work needs to be done for too little gain, OTH it might be nice for people who do not want to use mod_rewrite for these comparable simple tasks.
