Demonstrates two ways of sending an HTTPS PUT application/x-www-form-urlencoded request. Delphi ActiveX

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

http := TChilkatHttp.Create(Self);

// The 1st example sends a PUT with the query params in the URL.
// The body of the request will be empty.
url := 'https://example.com/leads/12345678?uid=XXXX&apikey=YYYYYY&notes=Test_Note';

// Sends the following request:

// PUT /leads/12345678?uid=XXXX&apikey=YYYYYY&notes=Test_Note HTTP/1.1
// Host: example.com
// Accept: */*
// Accept-Encoding: gzip
// Content-Length: 0

  end;

// -----------------------------------------------------------------------
// Now we send the same request, but instead the query params are in the HTTP request body.

// Host: example.com
// Content-Type: application/x-www-form-urlencoded
// Content-Length: 38
// 
// uid=XXXX&apikey=YYYYYY&notes=Test_Notereq.HttpVerb = "POST";
