ARR Overview

If you use SDL Contenta, IIS, and Tomcat together, you need to set up ARR.

Microsoft Application Request Routing (ARR) for IIS is a proxy-based routing module that forwards HTTP requests to content server based on HTTP headers, server variables, and load balance algorithms.

Upgrade
If you are upgrading Contenta and you are currently using the ISAPI redirector to use IIS 7 or higher in conjunction with Apache Tomcat, replace ISAPI with ARR.
Installation
In an installation scenario that combines Contenta, IIS 7 or higher and Tomcat, set up ARR.
