Hi All,
I have gone through some of the articles on ws-addressing, but couldn't
actually figure out why ws-addressing is required ?

what I understand from ws-addressing is that using ws-addressing a
response can be addressed to some other destination. For e.g. client-A
invokes a service at Server1 and requires the response to be sent to
Client-B. ws-addressing provides the standarized <wsa:ReplyTo> MI
header to achieve this. The client client-A will send a SOAP message
with <wsa:ReplyTo> element containing the url of destination endpoint
where response is to be made, in SOAP header. The server when find
<wsa:ReplyTo> element in SOAP header, will send the response to the
specified url.

Similarly From header is to send the acknowledgement back to the sender
& FaultTo to send the fault to sender/other fault handler.

Utility of EPR's (End Point Reference) is also vague.

Is this the only scenario where ws-addressing should be implemented ?

Comments/Suggestions are welcome.
