(JavaScript) REST Send multipart/form-data
Demonstrates how to send a multipart/form-data HTTP request.
var success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var rest = new CkRest();
// Connect to the destination web server.
var bTls = true;
var port = 443;
var bAutoReconnect = true;
success = rest.Connect("www.somewebserver.com",port,bTls,bAutoReconnect);
// 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.
// POST /some_path HTTP/1.1
