    //  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.

    //  call AddFileForUpload instead.

    //  The 1st arg is the filename passed in the HTTP request.
    //  The 2nd arg is the path in the local filesytem.
    //  The file is not loaded into memory.  It is streamed directly from the file
    //  when the HTTP POST is sent.
