I have an ASP Menu object that's pulling data from a SiteMap XML file. On that menu, I have a link to my login page. When I click the link and login (which fires on a button event), the Menu does not exposed the protected links. I suspect it has to do with the security context not being updated in time for the render, but I don't know how to trace that. Any page refresh works fine, of course. So, I guess my question is how to I switch to an authenticated context immediately?
