(C#) HTTP HEAD RequestSends 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 = http.GetHead("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. Debug.WriteLine("Status Code = " + Convert.ToString(resp.StatusCode)); Debug.WriteLine("Status Line = " + resp.StatusLine); Debug.WriteLine("Status Text = " + resp.StatusText); Debug.WriteLine("Full Response Header:"); Debug.WriteLine(resp.Header); Debug.WriteLine("----"); int numHeaderFields = resp.NumHeaderFields; Debug.WriteLine("Num Header Fields: " + Convert.ToString(numHeaderFields)); int i; for (i = 0; i <= numHeaderFields - 1; i++) { Debug.WriteLine(resp.GetHeaderName(i) + ": " + resp.GetHeaderValue(i)); } |
