We've some selfprogrammed subpages outside the YAF-Installation, but in its folder like a chat and a portal. If a user tries to open the chat.aspx, he has to log in. We check this with

if (this.PageContext().IsGuest))

But if the user tries to open the chat, he has to login for more than one time. It seems, that the session can't be read or something else.

On PageLoad, we add a YAF session like this:

YafWebService serv = new YafWebService();
serv.Session.Add("Chat Session", null);

Is there a workaround for the session handling? Can anybody help us? Thanks a lot.
