Nitrogen's default routing handler allows you to use 'Smart Extensions.' A smart extension lets you provide an different entry point into a module that may or may not get pre- and post-processed in a standard way based on the extension provided to the filename. The most common smart extension might be appending a .json which might then return a .json encoded data structure, complete with the appropriate MIME-type set.

This demo uses Nitrogen's built-in JSON Smart Extension which, if the request has a .json extension, Nitrogen will call json_main(), which is expected to return an Erlang proplist. The proplist will automatically be converted to a JSON string and the MIME-type will be set to "application/json"
