Archived:Implementing Automatic Web Service Authentication using Symbian C++
A web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically Web Services Description Language (WSDL)).
The S60 Web Services Framework (WSF) API abstracts the details of connecting to and communicating with a Web service. It also provides helper classes for sending requests and handling the responses of Web services.
A Web Services Consumer (WSC) application can directly connect to a basic Web Service if it does not involve any authentication. However, if authentication is enabled, an authentication dialog is popped whenever the consumer application tries to establish a connection. The authentication dialog can be avoided by using the following code snippet before starting the connection.
