title: What I should do to make a html file load different page every time the user open it?
body: <p>This is the content of my html file : </p>
  
  <pre><code>&lt;meta http-equiv="refresh" content="0; url=http://google.com" /&gt;
  </code></pre>
  
  <p>So, when the user open it, it will be redirected to google..
  But what I want is write a script inside the file  that can change the url/the page that will be loaded  every time the user open it.</p>
  
  <p>Example:
  first time open google
  second time open facebook
  and then, start over.. open google, and so on.</p>
  
  <p>Any idea please  how can I do that?</p>
