This one is actually part-ii of my first blog “Running multiple tomcat instances with Coldfusion standard version - Part I” but to make it more meaningful I have changed title of this Post.

In previous post we have run single site on two instance of tomcat and on different port. Now time to run both instance under single website URI with load balancing for high availability under Apache server.

Let's install Apache http server using downloaded .msi, to avoid security issue and spacing in path I prefer to install “C:\Apache2.2” [APACHE_HOME] and make sure it is pointing to port 80. Once finish with installing browse URL http://localhost to make sure Apache server is configured and running correctly. To perform load balancing on two tomcat instance download mod_jk. Use Binary releases link and choose your appropriate platform and download file mod_jk-1.2.31-httpd-2.2.3.so. Copy it to APACHE_HOME/modules folder and rename it to mod_jk.so.

Since couple of weeks I was working with Railo and ColdFusion 9 (standard edition) to clustering and load balancing. I have started with Railo as I was new to Railo and keen to work around it. I wrote several post about Railo installation
Installing RAILO Tomcat on windows step by step
Installing RAILO Tomcat on windows step by step - part ii
Running multiple instances of RAILO on tomcat.

Now it turn of ColdFusion for load balancing. I have googled it about but mostly found articles with enterprise edition and it is easy to implement but I want to work with developer/standard edition. Below is step by step instruction to running multiple ColdFusion (standard edition) instances on one computer.
