title: Fetching in javascript with absolute url and relative url
body: <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>
