    // 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 entire contents of the files.
