Can you add an option to block all audio and video media from going through the connection?
Too many Web sites are an utter waste of bandwidth with their video, even if it's supposedly part of the content.
For anyone who tethers their laptop to a mobile connection, this is an issue.
This is easily done via script. Rules > Customize Rules > OnPeekAtResponseHeaders. If the Content-Type starts with video/ or audio/, then you call .Abort() on the Session.
Having said that, some audio/video is delivered with the wrong content type.
