NavigatingCancelEventArgs encapsulates the following details of the navigation request:
Navigation Request: WebRequest.
This information allows you to both evaluate the nature of the navigation request, and view and update specified request details before navigation occurs.
Based on the navigation request information provided by NavigatingCancelEventArgs, or based on application-specific state or code, you can completely prevent navigation by setting the Cancel property to true (by default, Cancel is false).
The following example shows how to handle Navigating to detect whether a request to refresh static content has been made and, if so, to cancel the request.
