title: VBA ServerXMLHTTP https request with self signed certificate
body: <p>I'm using a ServerXMLHTTP object to make some http requests on an excel 2007 vba script.</p>
  
  <p>But I need to connect to an https server which uses a self-signed SSL Certificate, so by default I get the message "The certificate authority is invalid or incorrect". Is there a way to configure the ServerXMLHTTP object so that it doesn't requires a CA Certificate?</p>
  
  <p>Some sample code follows:</p>
  
  <pre><code>Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
    objHTTP.Open "POST", "https://invernalia.homelinux.net", False, "user", "password"
    objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
    objHTTP.send ("")
  </code></pre>
