Title: Session data (cookies, user-agent) is not being sent for encrypted HLS streams

This causes services like Akamai to give a 403 forbidden when requesting the TS files, because they expect the same cookies and user-agent on all requests.
Common problem for AirPlay in XBMC because many sites use Akamai for HLS streaming.
