' 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.
req.AddHeader "Expect","100-continue"

' Set a photo caption.
req.AddParam "caption","Here are some penguins!"

' Additional parameters can be added to the request by 
' calling AddParam once per parameter.
