Processing SOAP Headers (O'Reilly) [LWN.net]

Rich Salz details SOAP header processing on O'Reilly. "In this month's column we'll look at how SOAP headers can be used to talk to an intermediate server that adds value to the basic search service. The value-add is actually pretty silly: we'll send the query, pick one of the results at random to return, and send it back as an HTML page in Pig Latin. Our goal, however, is to understand how to process SOAP headers, and why you'd want to do so. But first I want to thank Google for providing a wonderful Web API, which it is, module the concerns I addressed in my first column. SOAP structures a message into two main parts: the headers and the body. I'll go out on a limb and say that almost all SOAP messages so far use the body. Very few put anything in the SOAP headers."
