Few new users will be served by that server. All existing users ‘sticking’ to this real worker will continue to be processed by this real worker. This will help reduce the number of users who will have to login again when the real worker is taken offline.After some time, the real worker is disabled and taken offline. Once it is ready to come online, the worker is enabled again in balancer manager.</div></p><p><div class="content">ProxyPass /apache-load-balancing-1.0 balancer://mycluster stickysession=JSESSIONID &lt;Proxy balancer://mycluster&gt; BalancerMember ajp://tomcat1:8009/apache-load-balancing-1.0 route=tomcat1 loadfactor=50 BalancerMember ajp://tomcat2:8009/apache-load-balancing-1.0 route=tomcat2 loadfactor=50 &lt;/Proxy&gt;</div></p><p><p><strong>Tags:</strong> <a href='http://www.diigo.com/user/pierre-yves/apache' rel='tag'>apache</a> <a href='http://www.diigo.com/user/pierre-yves/tomcat' rel='tag'>tomcat</a> <a href='http://www.diigo.com/user/pierre-yves/load-balancing' rel='tag'>load-balancing</a> <a href='http://www.diigo.com/user/pierre-yves/clustering' rel='tag'>clustering</a> </p><p><strong>Posted by:</strong> <a href='http://www.diigo.com/user/pierre-yves'>pierre-yves</a></p> Wed, 14 May 2008 09:28:52 -0000 60
