What port does Netflix device streaming use?
Is this port also used by the website direct streaming in the Silverlight app? What is the HTTP Content-Type if it uses port 80? Thanks.
Playback session(s) on devices are almost identical for browser-based sessions. The service uses HTTP and HTTPS session protocols (SSL-443) to netflix's CDN (https://moviecontrol.netflix.com)
Take a look at Pomelollc's blog here for a more detailed explanation of Netflix's video streaming security framework.
