Header Role

[Shankar sanjay]

Hi, I am not quite clear about role in SOAP Header?

It has value like next,none,ultimateReceiver.

Can anyone please explain with an example why we need this? and when we have to use this?

Hi!
Headers in SOAP messages can be used to send out-of-band information with a SOAP message, such as security credentials, transaction information etc.
There once was an idea that SOAP messages could be send not only directly from client to server, but passing a number of intermediary nodes along the way to the server.
Each node along the way can have a role (more like a name) that can be used to target headers to a specific node.
In reality, I rarely, if ever, see intermediary nodes.
Best wishes!
