//  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 AddFileForUpload2 for each file to be uploaded in the HTTP multipart/form-data POST
//  To allow Chilkat to determine the content-type automatically based on file-extension,
//  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.

//  http://www.mywebserver123abc.com/rcvFormDataUpload.aspx
