Thanks for your reply Chris. Client 1 profile showing up on Client 2 browser, if both client login to the web servers . Unfortunately, we get around 500 user login daily and only reported issue one or two user randomly. Can't recreate the issue.

=========================
clients ----Akamei proxy------(VS)-LTM-(pool)---- 2 Backend servers
1. VS configure with OneConnect with /32.
2. using VS ip address as source NAT to Backend servers.
3. using cookie hash persistence with match across VS.
