So it's about that time again, and March Madness will be upon us. Using MWG 7.3.2, we would like to block just the video content from any sites hosting March Madness feeds. I have found that building my rule based on category will not work. For example, the sports site nbcsports.com contains links to videos that are hosted on a site categorized as Business. I have also created a rule with parameters URL.Category at least one in list <sports> AND MediaType.IsVideo = true and this does not work. Has anyone out there written a rule that successfully blocks this specific traffic? Thanks!
You found exactly what I was going to say, the video itself doesnt always come from a site categorized as sports. As such the rule you described would not work.
Perhaps you could use the Referer's category URL.CategoriesForURL(Header.Request.Get('Referer')) to check if the video originated from a sports related site.
