(Classic ASP) 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..)
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <% ' This example assumes the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. ' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http") set http = Server.CreateObject("Chilkat.Http") ' If the URL uses "https://", then the connection will be TLS.
