Get URL from middleware
===

I'm using python and the Google App Engine. I've added a Middleware class to my code, which is working fine. But now i need to know which URL is called in the Middleware class. I'm don't know how to get the URL from there.

This is what i have:

    class OtherClasses(BaseHandler):
        def get(self):
            # some code...
        def post(self):
            # some code...
    
    class Middleware(object):   
        def __init__(self, app):
            self.app = app
        def __call__(self, environ, start_response):
            #logging.debug("Setting namespace..." + namespace)
            
            print(self.request.url) #<--- Doesn't work in here...?
    
    
    app = webapp2.WSGIApplication([ROUTES], debug=True, config=webapp2_config)
    app = Middleware(app)

Appearently the **self.request.url** doesn't work in the middleware class. Anyone any idea how i can get the URL (or the route) that i'm currently in??
