Hi,

I am trying to figure out what may cause the following problem.

Several users are accessing a Wowza via a Squid proxy. The site uses jwplayer 6. Clients have the latest flash-player installed and active. Wowza listens on 1935 and 80.

Problem: only the first video plays. As long as one video is playing on gets "Error loading stream: Manifest not found or invalid" for the other videos.

I had a look with wireshark and can see that the second and following requests for the SMIL are answered by a new session id. That surprises me.

First attempt looks like this:
.

So that looks as expected. The SMIL is loaded, the connection is attempted, the player realizes it has to go via the proxy, opens a new stream, gets an id and happily plays the video.

But then the second attempt to get a SMIL looks like this:

The id 1948670105 is never used anywhere later. I wasn't expecting an id anyway, as the player sent a GET for a SMIL, not a POST to open a new stream.

What may I be doing wrong?
