Problem
            HTTP Scan policy rules for Large File Handling, are not being applied. IWSVA is deployed
               in ICAP mode in combination with a BlueCoat ProxySG.
            Reason
            At the time of IWSVA release, BlueCoat devices did not support the necessary ICAP
               protocol features required for Large File Handling.
            Solution
            Use either NetCache or Cisco CE cache server; otherwise, check for BlueCoat updates
               that may have added support for full duplex ICAP transactions.
