I tried implementing load balancing using mod_jk with two tomcat instance.
It holds good except for the case of spring security check. When i try using j_spring securitycheck. it is not working. Upon googling, this is what was the solution provided.
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_module modules/mod_proxy.so
ProxyPass /j_spring_security_check ajp://localhost:8009/j_spring_security_check
ProxyPass /j_spring_security_logout ajp://localhost:8009/j_spring_security_logout
When i use the above it is working. But the problem is, I will not be able to refer the second tomcat instance.
httpd.conf :Configurations are
LoadModule jk_module modules/mod_jk.so JkWorkersFile conf/workers.properties JkLogLevel info JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" JkLogFile logs/mod_jk.log JkMount /restservice/* lb JkMount /images/* lb <Location /jkmanager/> JKMount jkstatus Order deny,allow Allow from all </Location>
Worker File :
worker.list=lb
worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker2.port=8070
worker.worker2.host=localhost
