// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

$rest = new CkRest();

// Connect to the destination web server.
$bTls = true;
$port = 443;

// This example will send the following multipart/form-data request.
// The Content-Length is automatically computed and added by Chilkat.
// It will be different than what is shown here.
// The boundary string is also generated by Chilkat and will be different
// than shown below.
