Chapter 1. HTTP connector modules
Red Hat JBoss Core Services includes two different HTTP connector modules that you can use to load-balance HTTP requests to a set of back-end servlet containers:
-
The Apache Tomcat connector (
mod_jk) supports the load balancing of HTTP requests to a set of servlet containers, while maintaining sticky sessions and communicating over the Apache JServ Protocol (AJP). -
The JBoss HTTP connector (
mod_cluster) is a more advanced load balancer thanmod_jk. Themod_clustermodule provides all the functionality ofmod_jkand additional features such as real-time load-balancing calculations, application life-cycle control, automatic proxy discovery, and multiple protocol support.
The Apache HTTP Server Connectors and Load Balancing Guide describes how to install and configure the mod_proxy and mod_cluster connectors. This guide also provides information about Online Certificate Status Protocol (OCSP) and includes 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 an archive installation of JBoss Core Services on Red Hat Enterprise Linux. For other platforms, use the correct paths for your respective installation, as specified in the JBoss Core Services Installation Guide.
Red Hat Enterprise Linux 6 is no longer supported and subsequently was removed from the documentation.
