title: Use RTMP over port 80 or RTMPT over HTTP, what would be best?
body: <p>We currently use CloudFront Streaming distribution with JW Player 6 and the RTMP protocol. However, some of our corporate users have told us that they can't see the videos and is because they have RTMP's port 1935 blocked.</p>
  
  <p>CloudFront support RTMP streaming over port 1935 and 80. And it also supports RTMPT streaming tunneled over HTTP.</p>
  
  <p>So I could choose to stream RTMP over port 80 or RTMPT that uses HTTP.</p>
  
  <p>Between these two, what option would be best to have better performance (and less problematic and error-prone) while avoid being blocked by firewalls?</p>
  
  <p>Thanks!</p>
