[users@httpd] mod_proxy_balancer and stickysession

[gm]

Hi,

we want to use mod_proxy_balancer to load balance a J2EE
application server. So stickysession is set to JSESSIONID.
First I had:

        <Proxy balancer://default>
          BalancerMember http://host1
          BalancerMember http://host2
          BalancerMember http://host3
          ProxySet stickysession=JSESSIONID
        </Proxy>

        ProxyPreserveHost On
        ProxyPassMatch ^(.*\.jsp)$ balancer://default$1
        ProxyPassMatch ^(.*\.do)$ balancer://default$1

But the session was not sticky. After some TCP dump and reading
a bit more documentation, it seems that mod_proxy_balancer
alters the sessionid by appending ".[number]".

So now I have:

        <Proxy balancer://default>
          BalancerMember http://host1 route=0
          BalancerMember http://host2 route=1
          BalancerMember http://host3 route=2
          ProxySet stickysession=JSESSIONID
        </Proxy>

        ProxyPreserveHost On
        ProxyPassMatch ^(.*\.jsp)$ balancer://default$1
        ProxyPassMatch ^(.*\.do)$ balancer://default$1

In all likelihood this works better. Is this the right way to
do it?

Regards,
Gerhard
