How to Refresh the Page on Back Button Click: A Comprehensive Guide to Solving the Routing Problem

Refreshed Page on Back Button Click: A Comprehensive Solution

Problem:

Routing traffic to a single index.php file using .htaccess is problematic with the back button. The code provided is unable to handle back button functionality, leaving users stuck.

Solution:

Option 1:

1. Create a new PHP file that includes headers to prevent caching, as shown below:

<code class="php"><?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();
?></code>

2. Add a link to this file in your HTML page, e.g.:

<code class="html"><a href="refreshpage.php">Refresh Page</a></code>

When the back button is clicked, the browser will load the refreshpage.php file, which will output the current time and force a page refresh.

Option 2:

1. Implement the following JavaScript code, which will detect the back button click and reload the page:

<code class="javascript"><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();}
}
</script></code>

This code uses a hidden input field to track the page's state. The onload event updates the value of the input field. When the back button is clicked, the value of the input field will be "yes," so it triggers the location.reload() function to refresh the page.
