Sharing sessions between different contexts

[Luis Javier Beltran]

Hi,   I have different modules of an application in different contexts, and I want that if a user is authenticated in one of them, this session would be valid if he enters any of the rest. The problem is that as soon as the passes to another module, he's requested to login again.   Which is better way to this, or should I handle these modules some other way?   Thanks!!   Luis Javier
