Help to configure -- Cookie based authentication

Hi,

Hard to say without knowing iRule attached to your VS. If you can post your iRule (please use Preformatted Code - without it it's hard to read iRule) it would help in finding reason.

As a first step in troubleshooting I would capture communication between client and VS on BIG-IP. If after sending POST BIG-IP is resetting connection then most probably there is some error in iRule - you can check it using tail -f /var/log/ltm | grep in BIG-IP CLI - look for iRule related errors, most probably TCL error.
