web services - PHP rest server authentication -

I am analyzing how Zend_Rest and tonic work have no validation, so I want to add my own. My only problem is that they use reflections and when you call a method, you have to add an authentication call every time

I was thinking of adding the authentication check in the manufacturer but again You can not stop the way you actually call.

Did anyone face this problem and found a good solution?

Why not expand Zend_Rest? Then you can add a method to handle the authentication when you consider it to be sensible if you overload an existing Zend_Rest method, you can always instantate the original method at the end of your method so that you can restart the whole method : Do not prepare.
