Copying header values from gateway request channel to reply

[gemini929]

Hello,

My current gateway follows a publish-subscribe-channel which adds SEQUENCE_SIZE, SEQUENCE_NUMBER and CORRELATION_ID Message headers tto the messages in its request-channel. After the gateway, I would like to group the messages back together using an aggregator and the headers that were added earlier.

Is there a way of copying header values from a request message sent to a gateway (http:outbound-gateway) so that they may be added to the reply message afterwards?

Those headers should be copied automatically to the reply Message. Can you provide the relevant configuration excerpt?
