Hi, i'm using apache 2.1.9beta and mod_proxy_balancer on an AMD Opteron 64 running SLES 9. It compiled well and it runs. There is one special thing: Case 1 : If i make a balancercluster like this [for every context 1 cluster] ProxyPass /web balancer://wpgcluster lbmethod=byrequests stickysession=JSESSIONID nofailover=On <Proxy balancer://wpgcluster> BalancerMember http://172.19.15.21:11800/web <http://172.19.15.21:11800/web> smax=15 loadfactor=1 BalancerMember http://172.19.15.22:11810/web <http://172.19.15.22:11810/web> smax=15 loadfactor=1 </Proxy> ProxyPass /som balancer://somcluster lbmethod=byrequests stickysession=JSESSIONID nofailover=On <Proxy balancer://somcluster> BalancerMember http://172.19.15.21:11800/som <http://172.19.15.21:11800/som> loadfactor=1 BalancerMember http://172.19.15.22:11810/som <http://172.19.15.22:11810/som> loadfactor=1 </Proxy> than it is all working without any errors GET /web/portal -> 200 OK GET /som -> 200 OK BUT: Case 2: If i put it all together, because i want to send all requests to the backend servers like this ProxyPass / balancer://somcluster lbmethod=byrequests stickysession=JSESSIONID nofailover=On <Proxy balancer://somcluster> BalancerMember http://172.19.15.21:11800 <http://172.19.15.21:11800> loadfactor=1 BalancerMember http://172.19.15.22:11810 <http://172.19.15.22:11810> loadfactor=1 </Proxy> or this ProxyPass / balancer://somcluster lbmethod=byrequests stickysession=JSESSIONID nofailover=On <Proxy balancer://somcluster> BalancerMember <http://172.19.15.21:11800/> http://172.19.15.21:11800 <http://172.19.15.21:11800/> / loadfactor=1 BalancerMember <http://172.19.15.22:11810/> http://172.19.15.22:11810 <http://172.19.15.22:11810/> / loadfactor=1 </Proxy> than with every Request i get a "403" and inside the error_log there comes a message like GET /web/portal -> 403 Forbidden GET /som -> 403 Forbidden [Fri Nov 11 11:38:03 2005] [warn] proxy: No protocol handler was valid for the URL /web/portal. If you are using a DSO version of mod_proxy, mak e sure the proxy submodules are included in the configuration using LoadModule. Case 1 is working, but Case 2 not! In Case1 Apache knows to send the request to the backend, but why not in Case 2 ? Any Clue ?
