//  See Global Unlock Sample for sample code.

//  This example constructs and sends the following HTTP request.
//  (The boundary strings will be different and auto-generated by Chilkat)

//  SOAPAction: invio
//  Content-Type: Multipart/Related; boundary="MIME_boundary"; type="text/xml"; start="mailto:rootpart@soapui.org"
