Pier Avenue 1950s by Ron Felsing.
Overview
By specifying an order for paths that can match multiple URLs, you're now able to implement strategies for interception and pipelines. Path info path parts come before exact path parts. Exact path parts come before parameterized path parts.
If you want to implement an authentication interceptor, create a script that matches everything in a sub-directory as it's path info. Redirect if the user is forbidden.
Also, parameterized path parts can now accept path info.
