title: POST Request from iOS (AJAX, https)
body: <p>I'm trying to make an AJAX POST Request from my iOS (Cordova) App. The API URL has a secure certificate on www.myDomain.ch but not without www.
  When I test the Request with a tool everything works. I also tried it in a React test application, and it worked.
  Only from my iOS App the Request causes in a 403 error. I've tried it with jQuery Ajax, fetch and axios. The Backend also has CORS enabled.</p>
  
  <p>My AJAX call looks like:</p>
  
  <pre><code>$.ajax({
     url: 'myurl',
     data: JSON.stringify(dataObject),
     method: 'POST',
     dataType: 'json',
     success: function(data) {
        console.log('success', data);
     },
     error: function(err) {
        console.log('error', err);
     }
  });
  </code></pre>
  
  <p>Requires iOS a special https certificate or is there something I have to add in the Request Header?</p>
