           Summary: mod_proxy_balancer does not handle sticky sessions with
                    tomcat correctly
           Product: Apache httpd-2.0
           Version: 2.1-HEAD
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: major
          Priority: P2
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: bachhube@fmi.uni-passau.de
                CC: bachhube@fmi.uni-passau.de


Apache Tomcat uses JSESSIONID values like
95C5BB2B084DB06938BF798FCF3B3994.tomcat2 for sticky sessions. "tomcat2" is the
route set in jvmRoute in the Engine element in server.xml. 

I expected that mod_proxy_balancer would match its path argument against the
part after the . from JSESSIONID, but it tries to match against the whole cookie
and fails obviousely. (in httpd-2.1.6-alpha/modules/proxy/mod_proxy_balancer.c,
find_route_worker function)

That way, balancer is useless as a replacement for mod_jk load balancing with
sticky sessions.
