HTTP HEAD Request

See more HTTP Examples

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.

Dim http As New Chilkat.Http

// If the URL uses "https://", then the connection will be TLS.
// Otherwise it will be TCP.

// 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..
