Comparing mod_proxy and mod_jk

Introduction

Apache 2.2 ships with advanced mod_proxy set of modules that have some of the mod_jk capabilities namely AJP protocol and integrated load balancer. 

AJP (Apache Jserv Protocol) with it's current version 1.3 is constant binary protocol. Constant means that the connection between web server and application server is presumed to stay open once established for the system lifetime. 

This in essence makes web server and application server a single system from the users point of view.
