Seeburger AS2: Proxy Error 502

Question

Hi guys,
I'm facing a problem using AS2 Seeburger Adapter.
When sending the message I'm getting the following error:
Could not deliver as2 message to partner: 502 Proxy Error
( The HTTP message includes an unsupported header or an unsupported combination of headers. ) # null
I've checked the AS2 Header message and I've got the following content:
POST /as2/HttpReceiver Connection: Keep-Alive
content-disposition: attachment; filename=1208788092268
Message-ID: <[email protected]1>
Subject: AS2 Message
Disposition-Notification-To: testcompanyAS2
AS2-To: receivertestAS2
Date: Mon, 21 Apr 2008 14:28:12 GMT
AS2-From: testcompanyAS2
AS2-Version: 1.1
content-type: application/octet-stream
begin test
1
end test
One of the things which is odd is why doesn't the AS2 adapter place the http://<server_used>:<port_used> before the "/as2/HttpReceiver".
Another thing is, shouldn't we have a line break after the POST?
It seems to me that this two problems may be raising the 502 exception...
Have you guys faced something similar?

Hi,
no, there shouldn't be any line break and the path is correct too..
First thing I'd check is the proxy settings. Is your partner's AS2 server in the same network? Or are you sending messages outside your network? Ask the network guys for a information about the proxy. Is this configured in your adapter properly (there is a proxy configuration parameter)? Because I think there is network issue now..
