Solution #00004613
Scope:
This solution applies to all Barracuda Web Filters, firmware version 4.0.x and above.
Answer:
If there is an exception to all web traffic, content category, or domain filter then HTTPS traffic filtering will only be included if you enable the HTTPS filtering option in the Block/Accept > Configuration page. If HTTPS traffic filtering is enabled and if an exception rule specifying a warn action is applied to HTTPS traffic, the request will be Blocked instead of Warned.
