Clients at a remote office are accessing a website that is against your company Internet policy. You change the action of the security policy that controls HTTP access from permit to deny on the remote office SRX Series device. After committing the policy change, you notice that new users cannot access the website but users that have existing sessions on the device still have access. You want to block all user sessions immediately.
Which change would you make on the SRX Series device to accomplish this task?
