Robert Basic has a quick new tutorial about chaining routes in your Zend Framework applications:

On a forum, there was a question today, about adding language “support” to the routes using Zend Framework. The guy wanted routes like /en/foo/bar or /de/baz. I wrote there an example for that using Zend_Router_Routes_Chain, so just posting that example here, too.

Custom routing allows you to define routes specific to your application without having to change the core libraries. In his example, he shows how to set up the routing objects and how to add them to the request's chain.
