Thanks Lewis, the grep appMapping.data does helps. I am trying to create some complete rules, i find some of the rules/openaapID use http pattern to detect user access, but like google hangouts: http://www.google.com/hangouts/ <http://www.google.com/hangouts/>, but when user use Google Hangouts, they usually use it inside the gmail web page, or some client ends. But the message text or hangouts call are encrypted by SSL, https, how can i catch the traffic from hangouts?
