title: Chromium's XSS auditor refused to execute a script
body: <p>This is a message from the Chrome Inspector:</p>
  
  <blockquote>
    <p>The XSS Auditor refused to execute a script in
    <code>http://localhost/Disposable Working NOTAS.php</code>
    because its source code was found within the request.
    The auditor was enabled as the server sent neither
    an 'X-XSS-Protection' nor 'Content-Security-Policy' header.</p>
  </blockquote>
  
  <p>... I have a couple dozen websites sitting on localhost on my notebook which I use for a big part of my workflow, and in the last couple days, after an updated Chrome changed something, pretty much all the websites' textareas' content is not being saved to file anymore.</p>
  
  <p>The code which was saving edits I made, is uniformly broken; I enter new text, click
  on <em>save</em> and my browser, instead of executing the file~writing subroutines in the script
  for the webpage I am working in, simply opens a new blank page.  If I then hit the back
  button, the textarea still shows the freshly added content, but in the file, no changes
  are being appended.</p>
