I've noticed this happening with management portal pages, docbook, and now this page:
When it times out, it heads over to our application's timeout page:
Why???
They are separate web applications: /csp/samples/ vs. /WebApp/
Our application code hard-codes the timeout page to Home.cls?CacheLogout=end. We use Password authentication; there are connection cookies but in the application's path /WebApp/
What, how ?
