I'm having a problem with one of my sites and its child portals. When a user enters the site and logs in, (including administrators but not hosts) as soon as they leave the home page they are logged out. If they login from the page they were headed to, they can go anywhere on the site and remain logged in. If they go back to the home page, and leave it again, they will be logged off. This happens even if they go to the home page from the home page. If the users is headed for a secure page they are taken to the logon page, if they are headed for an All Users page they are just quietly logged off.
This only happens on portals that are accessed using the child name such as www.domain.com/child If the same portal is accessed via an alias such as www.child-domin.com the problem does not occur.
This has be come particularly problematic on my ecommerce portals.
I've searched as best I could and I find references to this problem a couple years back, but never any solution.
Any help would be appreciated, even theories at this point....
Thanks,
Rob
