I have Forefront TMG 2010 (sp2) configured to block Streaming Media, and Online Communities categories (www.youtube.com; www.facebook.com), while these rules works great in IE and Firefox; somehow Google Chrome manages to evade these rules. From searching online, I've read that this is due to Chrome behaving like a firewall client.
My question is, is there a way to prevent Chrome from behaving in this manner to effectively block URLs. If not what steps can be taken to completely block Google Chrome from accessing the internet.
