public HRESULT get_Uri(LPWSTR * uri)
True when the navigation was initiated through a user gesture as opposed to programmatic navigation.
public HRESULT get_IsUserInitiated(BOOL * isUserInitiated)
True when the navigation is redirected.
public HRESULT get_IsRedirected(BOOL * isRedirected)
The HTTP request headers for the navigation.
Note, you cannot modify the HTTP request headers in a NavigationStarting event.
The host may set this flag to cancel the navigation.
public HRESULT get_Cancel(BOOL * cancel)
If set, it will be as if the navigation never happened and the current page's content will be intact. For performance reasons, GET HTTP requests may happen, while the host is responding. This means cookies can be set and used part of a request for the navigation.
Set the Cancel property.
