I've been working on an app and am having a problem with a user details control.

I've got a user control on five pages, it's dynamic depending on if you are logged in (using Commerce Server IsAuthenticated method). When I am not logged in, everything is as it should be (a generic 'you're not logged in' message).

When I do log in, it changes and displays some of my details, but (and here's the problem) it changes on only two of the five pages. So when I browse around the rest of the site, my generic user details message is displayed again.

I've looked into the possibility of a cacheing problem but have been unable
to resolve it. The problem doesn't appear to be browser cacheing because CTRL+F5 doesn't change the display. Also I have not explicitly altered any of the inherant cacheing in the codebehind.

Has anyone experienced this before and can you offer any help?
Thanks, Mark.
