1 - In my application, each time i log in, i want to remove all the attributes of my application that are in Application and Portlet Scope.

Is it possible?

2 - This question is related to question 1. I've an application that needs authentication to enter. In the application, i have a main page of my application (Page A). From that page i access another page (Page B). For example: I'm in Page B, and i do log out. Now, when i enter in my application again, i want to go to Page A. What is happenning to me, is that i'm going to Page B. How can i solve this problem?

Thanks,
Pedro
