# Description:  This script will tunnel an HTTP cache connection over SSH so
#               that you can do off site testing of HTTP IP address access
#               control/filtering restrictions through an external system
#               while on a heavily firewalled LAN with limited exit ports
#               allowed. Note: The browser should be configured to use the
#               cache as if it was running on the localhost (loopback
#               interface).
