Thanks Massimo. Again, i am so new to web development. I learned from your web2py book that your framework goes through a series of actions and i am assuming it creates objects in memory and fills these objects with user data and then processes these objects according to the model, controller and view code written for that page request.
Is there a way of looking at the various web2py objects in memory at different instances of time for one http request ?. For example, when a user submits a login form from browser, it gets to web2py and then web2py sets up the enviroment (request, response, cache, session etc objects created in memory and populated with information contained in that post request from browser) . Now is the auth object created in memory with the user inputs of username and password at this time ?. IF so, how can i see the contents of this objects at this time before web2py proceeds further?. Then web2py runs the model python code and then runs the controller. Finally the view. I could be changing the content of the objects, for example, the login form object anywhere in this chain - in model code, controller code or view code. Can i see how it is modified before it gets converted to html by the response object ?. And then can i see the final html code it generated at server side ? Finally, when the html code from server reaches the client, the browser can show me the source code and i get to see what web2py has done. But i want to see the intermediate actions also....
