Wildcard Loader Arguments

Using Drupal wildcard loader to access $_POST variables in my hook menu page callback

The Issue

Some specific tasks on Drupal-based API development which involves processing third party data like incoming ajax calls or POST requests may require that you will have to deal with these POST params directly somewhere within your drupal code but they might be not be available at the point due to other modules acitions or whatever.

By default, when data flow containing POST or GET values comes to page callback function defined in hook menu, those variables are usually available and accessible.
