Hey Guys,
From my reading of the MQ/broker documentation, you need three things to be able to handle user defined headers in the broker:
1. A parser implemented in C. Otherwise you can not access or update the header.
2. The header structure itself.
3. Custom input nodes to be able to properly construct the message tree that have the new headers. This also requires the parser mentioned above.
Am I right?
Has anyone implemented a user defined header/parser here?
Why would you do that rather then putting the information in the message body or in a seperate message that can be coorelated to the message?

I would expect that a user defined header would get dumped into the message body, since it should come after the mqmd.

So you should be able to handle it by processing using BLOB data or an MRM multi-part message.

I think.

Of course, if there were ALSO an MQRFH2, then there might be some problems.

But why would you add a custom header after an MQRFH2, since you could put all the extra info you needed IN the RFH?
