>Hi! I have 3 solutions each containing their own project. I run the first project in solution 1 (FIportal). I then have a link to direct the user to either a project in solution 2 (fabalrev) or a project in solution 3 (FAReqs). I setup session variables in project 1 which carry over fine to project 2. But, when I click the link to redirect to project 3, the session variables are lost. The watch window says "Session.get_Item has returned Null." EnableSessionState = "true" on all page directives in the HTML. I'm also importing System.Web.SessionState in the code-behind pages. What am I missing??
