How to prevent index.php from caching?

There are a few ways to prevent the index.php file from caching:

1. Disable caching for the index.php file in your server configuration. You can do this by adding directives in your .htaccess file or server configuration file to disable caching for the specific file.
2. Add cache-control headers to the index.php file. You can add headers to prevent caching in the PHP code of the index.php file itself. You can do this by adding the following code at the beginning of the index.php file:

1
2
3

header("Cache-Control: no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
header("Expires: 0");

1. Use versioning in the URL of the index.php file. By including a version number or timestamp in the URL of the index.php file, you can ensure that the file is always requested fresh from the server, rather than being served from cache.
2. Use a cache-busting technique. You can add a query parameter to the URL of the index.php file that changes every time the page is loaded, forcing the browser to request a fresh copy of the file. For example, you can append a timestamp or a random number to the URL like this: index.php?version=123456.

These methods can help prevent the index.php file from being cached and ensure that users always get the most up-to-date version of the file.
