I have a module that after completing a form, the user is added to a role.  The code seems to be working, but there is a delay between when the user is added to the role and the time it takes affect.   After adding the role, i would like to redirect them to a page that only enable for members of that particular role, but I get an error message that the user doesn't have permission.  However, if i wait about a minute and refresh the screen he does have the permission.  I can also log out and and log back in and immediately have the permission.

I'm sure i'm missing something simple, clearing or reloading some variables, but I haven't been able to identify the right method.

Can someone point me in the correct direction?

As i mentioned,  I'm not seeing that to be exactly true.  If i have a public role, and pages that are only accessible by that role,  i can subscribe under the member services pages,  wait about 1 minute and I have access, without logging out and back in. 

And if it were true, I should still be able to make the calls to the correct code to simulate re-logging in. 

I've tried these 2 routines but with no success.

DataCache.ClearUserCache(objUserInfo.PortalID, objUserInfo.Username)

I have run into this same issue.  Did anyone ever come up with a good fix?
