Hi Amar,

Came across this KB on the topic, looks like it was published before the release of V5, but I think the key point is that if you are looking to block access to https sites you need to be running in one of the proxy modes and need to be redirecting https to the SWG proxy for this to happen.

Kevin is correct to block https traffic you must be running in a proxy mode and the machines must be using SWG as a proxy.
