Load balancing problem

[Brendan.McKenna@xxxxxxxxx]

Hi,

        I
am running httpd version 2.2.6 on Windows XP SP2.  I am trying to
use sticky sessions to route users to a server, based on the value of the
JSESSIONID cookie in their request.  While the load balancing does
appear to work, the sticky sessions don't appear to be working.  My
configuration looks like this:

ProxyRequests   Off
<Location /selfcare>   
    ProxyPass balancer://selfcare
stickysession=JSESSIONID 
</Location>
<Proxy balancer://selfcare>
    BalancerMember http://host1:1109/selfcare
loadfactor=1 route=1
    BalancerMember http://host2:1109/selfcare
loadfactor=1 route=2
    ProxySet lbmethod=byrequests
    #ProxySet lbmethod=bytraffic
</Proxy>

        The
error.log file, however contains the following, which appears to me to
mean that even though it's finding the JSESSIONID cookie, it's not routing
the requests to the same host:

        Have
I stumbled across a bug, or am I doing something wrong?  Any help
would be greatly appreciated....
