Service Contexts
Figure 21-5 View the Service Context on the Client Reply
When processing the client reply, although the client’s context cannot be updated by the reply’s service context, the service
may still wish to query the service context information.
The client’s context cannot be updated because such updates would be invalid on asynchronous calls. The client thread may
be continually changing its context and if a reply also changed the context at any time, the state of the context at any given
time would be indeterminate.
The requirements that exist in Section 21.1.2, “Client Sends Request,? on page 21-3
also exist here.
