// Send an "Expect: 100-continue" header in the request.
// This causes the HTTP server to end a 100-continue response
// immediately after receiving the HTTP header.  The client
// (Chilkat) will receive this intermediate response, and if
// it's not an error response, it knows that the HTTP server will
// accept the data that is forthcoming.
// The alternative is to get an error response after trying to upload
// the entire contents of the files.
