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....
