The customer as some requirement to authorize the download of encrypted files.
How can this be achieve in a Proxy SG policy?
In this example, the administrator has chosen to allow access to files that fail scanning because of password protection.
The scanning property must use the optional fail_open setting, and that the rules must also allow an error code of none. Also, the example assumes a user-defined exception page named virus_scan_failure.
response.icap.error_code=!(none, password_protected) exception(virus_scan_failure)
The reponse.icap.error_code condition is detailed on the "ProxySG Content Policy Language Reference" documents .
