Fetching in javascript with absolute url and relative url
<p>I have a script that I run on my local server and that fetches a php file (on the local server too). If I write the url to fetch as a relative path, I get the file without problems, but, if I add the 127.0.0.1/mypath/myFile, I get a 403 error.</p>

<pre><code>function localServerCall() {
    var urlLocalServer = '127.0.0.1:8000/mypath/myfile.php';
    //var urlLocalServer = 'myfile.php';   //THIS WORKS!
    fetch(urlLocalServer).then(function(response) {
      console.log(response.json);
      return response.json();
  }).then(function(data) {
      console.log(data)
  }).catch(function(err) {
      console.log ('ERROR LOCALSERVER', err);
  })
}
</code></pre>

<p>I was wondering if there are some limitations on the use of absolute/relative urls with fetch or if this problem might be due to something else.</p>
