Hi Mario >Your use case is pretty sophisticated.
I don't think, this use case is so sophisticated. Thinking about ajax applications, running multiple instances of the application in different browser windows. When loging on, it is nice, because you only have to do this, when stating the first instance of the application. Everything works fine so far. The problem occurs, when login off. As soon as you log off out of the first instances of the applications, all instances loos their (security)context, resulting in broken ajax communication! Pretty messy to capture and solve properly :-) best regards Matthias Gerber
