Anyway to disable "Confirm Form Resubmission" on Google Chrome?

The "Confirm Form Resubmission" message in Google Chrome typically appears when you try to refresh a page that was accessed through a form submission (POST request). Chrome is warning you that if you proceed with the refresh, the form data may be resubmitted, leading to duplicate submissions or undesired actions.

To disable the "Confirm Form Resubmission" warning in Google Chrome, you have a couple of options:

1. Use Redirect After POST (Recommended): The best way to avoid the "Confirm Form Resubmission" message is to use the "Redirect After POST" pattern. After processing the form submission on the server, redirect the user to another page using a GET request. This way, when the user refreshes the page, it will be a simple GET request instead of resubmitting the form data.

   For example, in your server-side code (e.g., PHP, Python, etc.), after processing the form submission, redirect the user to another page using the header() function (in PHP) or the appropriate method in your server-side language.

2. Prevent Cache for POST Requests: Another approach is to add a Cache-Control header to your server response for POST requests. This will instruct Chrome not to cache the page, and therefore, when the user tries to refresh, Chrome will make a new POST request rather than displaying the confirmation message.

   In PHP, you can add the following code at the beginning of your script to disable caching for POST requests:

   phpCopy code
   <?php
   if ($_SERVER['REQUEST_METHOD'] == 'POST') {
       header('Cache-Control: no-cache, no-store, must-revalidate');
       header('Pragma: no-cache');
       header('Expires: 0');
   }
   ?>
   

   This will set appropriate headers for POST requests to prevent caching.

However, keep in mind that completely disabling the "Confirm Form Resubmission" warning can lead to unwanted behavior for some users, especially when they are dealing with sensitive actions (e.g., submitting payment information or performing actions with potential side effects). Using the "Redirect After POST" pattern is the recommended and safer approach to handle this situation.
