You need to configure the CredentialPicker object to meet the requirements.
Which code segment should you insert at line GC04?
Which line of code should you use?
You are developing a web page that consumes a Windows Communication Foundation (WCF)
service. The page includes the following code segment.
var xhr = new XMLHttpRequest() ;
The page uses the xhrHandler() method to listen for changes to the request status of the WCF
service calls. It uses the xmlToJavaScript() method to convert the response from the WCF service to a
JavaScript object.
The xhrHandler() method must be called automatically each time the request status changes.
You need to add the event handler to the request object.
