Remapping Apache to a TC backend, but I would like to filter out unless a certain parameter is set.
ie. http://server/myapp?project=mine maps to http:server:8080/myapp?project=mine
There will be more parameters (though I will enforce project=mine as the last).
ProxyPassMatch works but not for parameters.
I tried
RewriteCond %{QUERY_STRING} project=mine
RewriteRule (.*) localhost:8080
Seems to be close, but testing in CURL I get: This document moved...
Which I do not get with ProxyPass or ProxyPassMatch
What am I missing ?
Tips/pointers/RTFMs appreciated
You need to use the P flag on the RewriteRule to pass the request through mod_proxy, as opposed to being treated as an external 3xx redirect (ie. "this document has moved" msg).
For example, if used directly in the <VirtualHost> container:
RewriteCond %{QUERY_STRING} (^|&)project=mine$
RewriteRule ^/myapp$ http://server:8080$0 [P]
The condition checks for the URL parameter project=mine at the end of the query string. Only the URL-path /myapp is matched (as in your example).
The $0 backreference contains the entire URL-path that is matched by the RewriteRule pattern. This simply saves repeating /myapp in the substitution string.
RewriteCond %{QUERY_STRING} project=mine RewriteRule (.*) localhost:8080
There are a few issues with your initial attempt (apart from the missing P flag):
/anotherapp would also be caught. But this is also discarded.project=mine matches that string anywhere in the query string, even as part of other URL params. eg. fooproject=miner would also match.localhost:8080 is not a valid substitution string.
