// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// 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).
