Title: Allow overriding of HTTP method 

Allow overriding of HTTP method used for matching via the "_method" request parameter. This allows people to use RESTful URL definitions even with clients that don't support all the HTTP verbs (i.e. most Javascript AJAX clients).

This feature is taken from Rails.
