(C# UWP/WinRT) HTTP HEAD Request

Sends an HTTP HEAD request and gets the response.

Note: The response to an HTTP HEAD request is always just the response header. The reponse body is always 0 length (thus the reason it's called a "HEAD" request..)

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

// If the URL uses "https://", then the connection will be TLS.
// Otherwise it will be TCP.
Chilkat.HttpResponse resp = await http.GetHeadAsync("https://example-code.com/");
if (http.LastMethodSuccess != true) {
    // A failure is when we don't get any response.  It could be a timeout, an inability to connect, etc.
    // For example, a "404 Not Found" response is still a response, and thus deemed success in terms of the API..
    Debug.WriteLine(http.LastErrorText);
    return;
}

// Examine the response.
