Thanks Anam, but we are looking at to use mod proxy for Apache/Tomcat Communication and session persistence. Can it be done using our requirement? Thank you, Regards, Kashif Rahman. From: Anam Ali Khan [mailto:anamalikhan@xxxxxxxxx] Hi, I would recommend HAProxy as a load balancer in your PHP + JSP application environment. It will work as follows: 1. First HAProxy will accept client request. 2. It will forward those requests to two machines via round robin 3. Each WebServer must use mod_jk as a connector (module) for Apache/Tomcat communication and session persistence. 4. HAproxy also perform health checking for two servers. -Anam From: Kashif Rahman <kashif.rahman@xxxxxxxxxx> Hi, We have requirement for to load balance our PHP + JSP application. I need to know that how can I load balance 2 Apache web Servers and 2 Tomcat Servers, 1st Web Server + Tomcat on 1st machine and 2nd Web Server + Tomcat on 2nd machine. We want to use Proxy Load Balancer for Apache to tomcat communication. If we use single Apache Web Server and 2 tomcat instances on different machines, it seems to be working and sharing session fine, but when we add 2nd apache web server to have fail over for PHP too, tomcat stops replicating session? If anyone is running such type of setup then kindly do let me know what could be the issues or anything missing. I am using Apache WebServer as a load balancer for both Apache too. Apache Webserver | | _____ |______ | | Apache Webserver Apache Webserver | | Tomcat Tomcat What could be the recommended solution for this requirement? Thank you, Best Regards, Kashif Rahman |
