Unhandled exception in GetRolesFromCookie

Hi Joe

I'm not sure if you'd count this as a bug, but it is an unhandled exception that has just occured to me on one of our mojoPortal sites... (and could happen to real site users).  After rebooting the web server, I had a browser window sitting there with a page that I had loaded before the reboot. On clicking a link I was asked to log in (I had previously been logged in already). On entering the login details, the site bombed with your standard "...something wrong, you might like to click back or visit the home page..." page.

I then checked on the server, stopped and started the site and app pool etc and no change. Then I found that the site worked fine in a different browser. Then I found this in the server event log (specifics obscured):

Event code: 3005

Re: Unhandled exception in GetRolesFromCookie

Hi Crispin,

This is the result of a change in behavior in the .NET runtime after a recent ASP.NET security update that came down via windows update. The security update came out right after we shipped mojoPortal 2.3.7.6 and this problem was reported on this thread.

I have patched the 2.3.7.6 release to handle this exception so upgrading should solve it.

Best,

Joe
