Hi all,On sites with large numbers of ProxyPass directives, these directives are matched in turn on every request, and this can take a lot of time, especially when we've already done a location walk.
A simple optimisation is to allow this existing syntax: <Location /foo> ProxyPass http://somewhere/foo </Location> to simply be a single mod_proxy alias in a per-directory context.If this syntax is used, the need to walk the proxy alias list is eliminated, and a significant amount of time is saved.
This also has the side effect that ProxyPass inside LocationMatch starts working properly (it was broken before):
<LocationMatch ^/foo(.*)> ProxyPass http://somewhere/$1 </LocationMatch>In theory, the "ProxyPass /foo http://somewhere/"; and "ProxyPassMatch ^/foo(.*) http://somewhere/$1"; syntaxes can be deprecated, as Location/ LocationMatch is way simpler to handle.
