Hello to all,
I am using Apache 2.2.21 & Tomcat 6.0.29
1) Schema: Load balancer (Apache.2.2.21) -> 1st appli (Tomcat 6.0.29)
-> 2nd appli. (Tomcat 6.0.29)
2) Using the following configuration, my load balancing is stateless instead of
statefull (having a look at the logs).
-------------------------------------------------------------------------------------------------------------------------------------------------------------
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<IfModule log_config_module>
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{UNIQUE_ID}e\"
\"%{BALANCER_WORKER_ROUTE}e\"" logjyc
CustomLog logs/jyc_log logjyc
</IfModule>
ProxyPass /MCSRootURI balancer://MCSCluster stickysession=JSESSIONID
nofailover=Off
<Proxy balancer://MCSCluster >
BalancerMember http://workstation1:MCSPort1/MCSRootURI route=host1
BalancerMember http://MCSServer2:MCSPort2/MCSRootURI route=host2
</Proxy>
ProxyPassReverse /MCSRootURI http://MCSServer1:MCSPort1/MCSRootURI
ProxyPassReverse /MCSRootURI http://MCSServer2:MCSPort2/MCSRootURI
-------------------------------------------------------------------------------------------------------------------------------------------------------------
3) Query
=> What have i missed on Apache or Tomcat side to get JSESSIONID taken into
account then have a statefull load balancing ?
4) Bypass: using the following configuration my load balancing is this time
statefull (having a look at the logs).
