Chapter 1. Introduction
Two different load balancing HTTP connectors are included with Red Hat JBoss Web Server.
- The Apache Tomcat Connector (mod_jk) supports the load balancing of HTTP calls to a set of Servlet containers while maintaining sticky sessions, and communicates over AJP.
- mod_cluster is a more advanced load balancer than mod_jk, and provides all of the functionality of mod_jk, plus other additional features. These include real-time load balancing calculations, application life-cycle control, automatic proxy discovery, and multiple protocol support.
This guide also contains information on Online Certificate Status Protocol (OSCP), and a set of working examples for basic load balancing, and Kerberos authentication using mod_auth_kerb.
Most file and directory paths shown in this guide are for a Zip installation of JBoss Web Server on Red Hat Enterprise Linux. For other platforms, use the correct paths for your respective installation as specified in the JBoss Web Server Installation Guide.
