RTMPT problems... HELP!!!

[ManMachine]

We're working on a big project with a Beta due monday. It's a flash network
game produced for a large Swedish bank. Since it's going to run on bank
computers, the firewalls won't allow anything but RTMPT traffic on port 80. Our
client and server side scripting works fine... except with RTMPT.

When we use RTMPT we can connect to the server and read information from a
SharedObject. We cannot however call or recieve calls for methods on the
NetConnection or se updates on the SharedObjects. After a while the connection
dies but the RTMPT-connected client does not notice. If other clients are
connected through RTMP, they can se the RTMPT clients connect and disconnect.

All connections are made on port 80.

Ideas anyone?

I have seen this kind of thing when connecting to clients across a proxy server
- an apparent initial connection, the connection fails silently. I have to say
that this doesn't happen very often, but it's worth investigating. When this
last happened to me I discovered that users on a site which used an Inktomi
proxy had this, but everyone else in the company had no problem.

Hi,

The problem is that we don't connect through a proxy. Do you have any idea of where we should start debugging?

Are you absolutely certain you're not connecting through a proxy? It's pretty
unusual for large organisations not to have some kind of proxy these days. I'm
starting from the assumption that your application works fine for RTMP, and
that the only difference between RTMP and RTMPT clients is the port and
protocol you use when you set them up. If this is the case, it seems that the
problem must lie between yourself and the user.

You could start getting someone who is having the problem to try this link:

If</a> there's a tunnelling problem it should show up there.

There are several articles about HTTP tunnelling, including:

I</a> suppose that a bank might have all kinds of security policies enforced
on its firewalls. It would be worth asking.
