Zend environment action parameter

I want to pass the whole path as an action parameter to the action of my controller.

mycontroller / MyAction / myparameter / path_value

eg. path_value could be something like test / folder / folder2

I do not want to specify a parameter. Is it possible that in my controller action I can get the whole path as the parameter value for "myparameter" (like "test / folder / folder2") instead of "test".

I hope I'm clear enough. Tnx in advance
