The customer noticed errornous "Modified ASM cookie" when the login->logout happened on a different web application.
The impact of this issue is a false violation of "Modified ASM cookie".
This issue occurs when you configure a login page enforcing and have two security policies on the same host.
This issue has no workaround at this time.
We fixed a TS cookie so that when a login page is configured in the security policy, after a user goes through the logout page, the system no longer erroneously issues the "Modified ASM Cookie" violation as it used to do in a specific scenario.
