Manage Web service status (2)

In the following example, the appMyServiceUsage status variable is accessed to increase its value. The following code example shows an XML Web service that uses two XML Web Service Methods: ServerUsage and PerSessionServerUage. ServerUsage is a click counter used to access the ServerUsage XML Web Service method, regardless of how the client communicates with the XML Web Service method. For example, if three clients call the ServerUsage XML Web Service method consecutively, the last client receives a return value of 3. PerSessionServiceUsage is a counter used for a special client session. If the three clients continuously access PerSessionServiceUsage, each client receives the same result during the first call.
