• When you start a Content Download from a WAP 1.x browser that is running over a secure connection, the Content Download agent typically establishes a new secure connection and leaves the browser’s secure connection in idle while the Content Download is ongoing. Often, the Content Download takes a longer time than the address/port mapping lease time in the NAT or firewall. If so, the address/port mapping originally used with the browser’s secure connection has been lost once the Content Download is over, and the WAP gateway is therefore not able to recognize the client again. Consequently, the secure connection of the browser is lost.
