What are the potential pitfalls of using PHP headers like Expires, Last-Modified, Cache-Control, and Pragma to control browser caching for dynamically generated content?
Using PHP headers like Expires, Last-Modified, Cache-Control, and Pragma to control browser caching for dynamically generated content can lead to issues such as inconsistent caching behavior across different browsers, difficulty in managing cache invalidation, and potential conflicts with other caching mechanisms. To address these pitfalls, it is recommended to use a combination of server-side caching strategies, client-side caching techniques, and cache-busting methods to ensure optimal performance and reliability.
// Disable caching for dynamically generated content
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
