Modifying httpd.conf parameters to enable sticky round robin

For the sticky round robin feature to work, make the following changes in the apache-install-location/conf/extra/httpd-mpm.conf file for Apache 2.2.x or in the apache-install-location/conf/httpd.conf file for Apache 2.0.x.

Under the section prefork MPM, ensure that the values of the parameters StartServers and maxclients are set to 1. Otherwise, every new session request will spawn a new Apache process and the load balancer plug-in will be initialized resulting in requests landing in the same instance.

For Apache 2.2.x, uncomment the following line in the apache-install-location/conf/httpd.conf file:

Include conf/extra/httpd-mpm.conf
