Seeburger AS2: Proxy Error 502

[Former Member]

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: <202528991113967900811208788092296.SEEBURGER.xidadm@111.111.111.111>

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?

What do you mean with "guys"? There was only me and I told you I think it was a network issue... No points 4 me?

But it's good to hear it's ok now. If you have any further question regarding to AS2, let me know..

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..

This maybe not just response from your proxy, but also partner's proxy, so check it too..

Hi Peter,

Thanks for your response.

After talking to the network team, I've checked the proxy settings and they're correctly configured in the IDirectory. Despite this fact, I agree with you, it seems to me that it is a network setting but until then I've to explore every possibility....

If you have any extra ideas I'll grateful I'll be posting if i've new developments.
