I use the default session behavior built into WWC that uses a cookie and stores the values in the session table. I don't have any busy sites to compare with but I know that others do and I don't think they have that problem. What version of WWC are you using?

>>I save the user id info in the session after the user logs in. The session info should stay intact until the user logs off, the session times out, or the user closes the browser down.

>>>This has been happening for some time. Our website appears to work without it but it has created some issues. We tie security features to the User ID, so it is important we track that down.
>>>Lately we have been sending it to a stale link page, but that's just a band-aid.
>>>
>>>Any help with this issue would be greatly appreciated.

>Yes. We actually use a mem file and we have a way of storing the session id on each link. Usually this isn't a problem. But for some reason, when we get a lot of traffic, the user id gets blanked out. Have you run into an issue like this?
