irules

iRules is a highly customized, Tcl-based scripting language allowing you complete programmatic access to application traffic in real time. If you’re looking to inspect, analyze, modify, route, re-direct, discard, or manipulate traffic in any way, chances are you can do it with an iRule. They even give you the ability to write business logic into your network layer.
