With all the variables and moving parts, a solid Dispatcher configuration is hard to achieve. And with its structure, it is easy to make small mistakes with large consequences. So, what can you do? Read on to find out.

Adobe has open sourced the Dispatcher Optimizer Tool (DOT) that parses and analyzes the Dispatcher configuration based on a set of extensible rules. It provides detailed information about the syntax errors it finds and configuration values that contradict best practices. It even includes the same scanning and analysis for the Apache Httpd configuration, if one is present. The findings are reported complete with file location and line number. Documentation links are included, explaining why the violations are important to fix, and how to fix them.

All that, and it is easy to setup and run using the DOT Maven Plugin!
->To learn how to use it, we are presenting a small, hands-on tutorial:

Quickly learn how to add a few lines to your pom.xml file, run the tool, scan the results, and fix a violation or two. It will help take the complexity out of the Dispatcher configuration — guaranteed!
