>                 Key: MODCLUSTER-351
>                 URL: https://issues.jboss.org/browse/MODCLUSTER-351
>             Project: mod_cluster
>          Issue Type: Bug
>    Affects Versions: MOD_CLUSTER_1_0_10_GA_CP04, 1.2.4.Final
>            Reporter: Aaron Ogburn
>            Assignee: Jean-Frederic Clere
>            Priority: Minor

> Looks like some compatability issues exist between Rewrites to the mod_cluster balancer and a ProxyPassReverse for it.  
> <VirtualHost *:80>
>    RewriteEngine On
>    RewriteRule ^/foo/(.*)$ balancer://mycluster/foo/$1 [P,L]
>    ProxyPassReverse /foo/ balancer://mycluster/foo/
> </VirtualHost>
> Requests served through the above VHost config fail with a 500.  The log shows:
> [Thu Aug 08 16:38:50 2013] [debug] mod_proxy_cluster.c(3448): proxy: CLUSTER no balancer for balancer://mycluster/foo/hi.jsp
> [Thu Aug 08 16:38:50 2013] [debug] proxy_util.c(1525): [client 127.0.0.1] proxy: *: found reverse proxy worker for balancer://mycluster/foo/hi.jsp
> [Thu Aug 08 16:38:50 2013] [debug] mod_proxy.c(1015): Running scheme balancer handler (attempt 0)
> [Thu Aug 08 16:38:50 2013] [debug] mod_proxy_http.c(1955): proxy: HTTP: declining URL balancer://mycluster/foo/hi.jsp
> [Thu Aug 08 16:38:50 2013] [debug] mod_proxy_ajp.c(664): proxy: AJP: declining URL balancer://mycluster/foo/hi.jsp
> [Thu Aug 08 16:38:50 2013] [warn] proxy: No protocol handler was valid for the URL /foo/hi.jsp. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.
> Removing the ProxyPassReverse, the request works again.  Looks like the balancer isn't found for some reason with both the Rewrite and ProxyPassReverse.
