What happens when a method call has been requested?
When a method call has been requested, the server has several options. It can return an HTTP error code or a SOAP fault containing a SOAP/application error, or it can return the results of the method execution. Both the fault and the method results use the standard SOAP payload syntax (that is, <Envelope>, <Body>, and so on).
