Topic: Load balancing syntax.

[olivier_giorgi]

Hello to all,

1) With Apache 2.2.4 the following statefull load balancing syntax is correct:
SetEnvIf ^Cookie$ "MYCOOKIE=([^ ;]*)" MYCOOKIE=$1
Header add Set-Cookie "MYCOOKIE=%{UNIQUE_ID}e.%{BALANCER_WORKER_ROUTE}e; path=/" env=!MYCOOKIE

ProxyPass /RootURI balancer://Cluster stickysession=MYCOOKIE nofailover=Off
<Proxy balancer://Cluster >
BalancerMember http://Server1:Port1/RootURI route=host1
BalancerMember http://Server2:Port2/RootURI route=host2
</Proxy>
ProxyPassReverse http://Server1:Port1/RootURI
ProxyPassReverse http://Server2:Port2/RootURI


2) Please, could you explain me why with Apache 2.2.4 the following statefull syntax is wrong:

ProxyPass /RootURI balancer://Cluster stickysession=JSESSIONID nofailover=Off
<Proxy balancer://Cluster >
BalancerMember http://Server1:Port1/RootURI
BalancerMember http://Server2:Port2/RootURI
</Proxy>

Apache 2.2.4 does not take into account the parameter JSESSIONID and the observed behavior is the same as a stateless load balancing.

Thanks in advance & have a good day.
Best regards Olivier.
