; This HTTP request contains binary data, so we cannot call GenerateRequestText
; to examine it as a string.  We can instead call GenerateRequestFile
; to write the request to a file and then examine using a hex editor,
; or an editor that is capable of handling null bytes and non-printable chars (perhaps by displaying "?" chars instead).
