Routes WSGI Middleware
Routing middleware that handles resolving the PATH_INFO in addition to optionally recognizing method overriding.
Create a Route middleware object
Using the use_method_override keyword will require Paste to be installed, and your application should use Paste’s WSGIRequest object as it will properly handle POST issues with wsgi.input should Routes check it.
If path_info is True, then should a route var contain path_info, the SCRIPT_NAME and PATH_INFO will be altered accordingly. This should be used with routes like:
map.connect('blog/*path_info', controller='blog', path_info='')
