Web Content Filtering (File in Motion)

Categories: File in motion
This filtering enabled traffic for websites of radio stations, but some does not block and passes like any website, now in this web site, not blocked, there is news video and audio, when I check the console and monitoring shows (as adjunata image).
So the idea is to block the traffic of those websites that do not exhaust.
In short, when entering a page, NOT can load a video or audio because it uses little bandwidth I have on the client.

Thanks.
