[users@httpd] rewrite proxy and query string
Just wondering if this is possible.
Due to a technicality, I would like urls on our site asking for
/dir/prog?gl/clouds.men*
to be reverse proxied from
http://another.domain.com/dir/prog?gl/clouds.men*
So I'm trying.
RewriteEngine on
RewriteRule ^(/dir/prog?gl/clouds.men*) http://another.domain.com/$1 [p]
Doesn't seem to work though by itself. For this to work though, the docs say for the P flag
"Note: mod_proxy must be enabled in order to use this flag."
Well, the module is loaded, but I'm not sure what I need to kick Proxy off. I tried these two
settings.
ProxyPassReverse /dir/prog?gl/clouds.men?gl/clouds.men http://another.domain.com/dir/prog?gl/clouds.men
ProxyPassReverse /dir/prog?gl/clouds.men?gl/clouds.men http://another.domain.com/dir/prog?gl/clouds.men
ProxyPassReverse /dir/prog?gl/clouds.men http://another.domain.com/dir/prog?gl/clouds.men
ProxyPassReverse /dir/prog?gl/clouds.men http://another.domain.com/dir/prog?gl/clouds.men
using either one of the above gets me a " proxy: No protocol handler was valid for the URL" error.
But perhaps since an argument in the query string is needed to proxy the approprate page,
I am simply out of luck, as the ProxyPass directive needs....
"a partial URL for the remote server and cannot include a query string."
I do not what _all_ the /dir/prog requests proxied.
Is what I'm trying to do possible? Any help is appreciated. Thanks!

I assume you're using Apache 2.x.
Did you load mod_proxy_http? mod_proxy is just a general wrapper for proxy
support, with mod_proxy_[protocol] you add the protocol-specific knowledge
to Apache, in your case you need the http knowledge.

In what part of httpd.conf are you placing this? It is best to place
it ouside any <Directory> section, in which case you need absolute
web-paths. The absence of a rewritelog would indicate that the
rewriterules are not coming anywhere near the request, since you
should get evidence even of missed matches.

Thanks for the tip, and I have looked into it. Acutally, right now, in my deconstruction of this,
I'm just trying to get mod_rewrite to rewrite _anything_!
RewriteEngine on
RewriteLogLevel 9
RewriteRule ^sda-bin(.*) ddl-bin$1
ScriptAlias /sda-bin/ /some/dir/ # doesn't seem to mater either above or below.
and a request to http://domain.com/sda-bin/m2h?gl/clouds.men returns as normal.
No rewrite logging comes through either. Maybe that doesn't get turned on unless
there's a match, but it should be matching. This module hold's it's secrets well. :(
thanx for any clues... and I have cleared my cache, and the access_log log's the
query as normal. Startup is fine, so the module must be loaded.

In the docs for RewriteRule, see the big box labeled "Query String".
You need something like:
RewriteEngine On
RewriteCond %{QUERY_STRING} ^gl/clouds.men
RewriteRule ^/dir/prog http://another.domain.com/dir/prog [P]
