Hi All, I've two webapps CoW and CoWTraining, each of which are load balanced by Apache 2.2.4 over two tomcat nodes running as services. i.e. two nodes for CoW and two for the other. This is set up in one server machine. Both the webapps are identical in functionality and operation but just that they are served by different hosts. The problem is that when I try to access CoWTraining in the same window after I access CoW, the server throws a 'Service Temporarily Unavailable' message. However, if I access CoWTraining first and then CoW, there are no problems. Also in this case, if I go further and access CoWTraining again there are still no problems. The error occurs only if I try to access CoWTraining in a window in which I've accessed CoW. There are no problems trying to access other applications in the same window. The reason I think this is related to apache is because I had both these webapps installed on one tomcat node and tested without the load balancing. My httpd.conf file has the following references to these applications in the same sequence. -------------------------------------------------------------------------- <Location /CoW> ProxyPass balancer://cluster-CoW/CoW stickysession=JSESSIONID nofailover=On ProxyPassReverse balancer://cluster-CoW/CoW </Location> <Location /CoWTraining> ProxyPass balancer://cluster-CoWTraining/CoWTraining stickysession=JSESSIONID nofailover=On ProxyPassReverse balancer://cluster-CoWTraining/CoWTraining </Location> <Proxy balancer://cluster-CoW> BalancerMember ajp://localhost:9209 route=tomcat70 retry=60 loadfactor=50 BalancerMember ajp://localhost:9309 route=tomcat71 retry=60 loadfactor=50 ProxySet lbmethod=bytraffic </Proxy> <Proxy balancer://cluster-CoWTraining> BalancerMember ajp://localhost:9409 route=tomcat72 retry=60 loadfactor=50 BalancerMember ajp://localhost:9509 route=tomcat73 retry=60 loadfactor=50 ProxySet lbmethod=bytraffic </Proxy> RewriteEngine on RewriteRule ^/CoW$ /CoW/ [R] RewriteRule ^/CoWTraining$ /CoWTraining/ [R] -------------------------------------------------------------------------- There are no errors in the tomcat logs.

I've already done a lot of googling with not much results.
