How to refresh page on back button click?

Question

I use .htaccess to route all of my traffic to a single index.php file. The code below to directs traffic, but for some reason it doesn't work with the back button. I don't know what to do to get the back button working. I've tried a variety of things and googled quite a bit and none of it has worked so I'm hoping someone here can help!

<?php
   if(isset($_GET['parameters'])) {
      if($_GET['parameters'] == "repair")
         include 'repair.html';
      else if($_GET['parameters'] == "training")
         include 'training.html';
      else if($_GET['parameters'] == "products")
         include 'products.html';
      else if($_GET['parameters'] == "about")
         include 'about.html';
      else if($_GET['parameters'] == "employees")
         include 'employees.html';
      else if($_GET['parameters'] == "training")
         include 'training.html';
      else if($_GET['parameters'] == "newaccount")
         include 'newaccount.html';
      else if($_GET['parameters'] == "contact")
         include 'contact.html';
      else if($_GET['parameters'] == "recommended")
         include 'recommended.html';
      else if($_GET['parameters'] == "careers")
         include 'careers.html';
      else
         include 'home.html';
   }
   else
      include 'home.html';
?>

So far I've tried and failed to use: window.onbeforeunload body onunload=""

There has got to be a way to onunload=location.reload() or something! Somehow has to know the syntax!!

Try this... not tested. I hope it will work for you.

Make a new php file. You can use the back and forward buttons and the number/timestamp on the page always updates.

<?php
header("Cache-Control: no-store, must-revalidate, max-age=0");
header("Pragma: no-cache");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
echo time();
?>
<a href="http://google.com">aaaaaaaaaaaaa</a>

Or

I found another solution:

The onload event should be fired when the user hits the back button. Elements not created via JavaScript will retain their values. I suggest keeping a backup of the data used in dynamically created element within an INPUT TYPE="hidden" set to display:none then onload using the value of the input to rebuild the dynamic elements to the way they were.

<input type="hidden" id="refreshed" value="no">
<script type="text/javascript">
onload=function(){
var e=document.getElementById("refreshed");
if(e.value=="no")e.value="yes";
else{e.value="no";location.reload();}
}
