Prevent Caching On First Open

Hello, WP Performance Score Booster Support Team,

I’m developing a performance improving plugin and have a specific caching requirement.

I need pages and posts not to be cached on first open, after they are created or edited.

I need to examine the page with all the JS and CSS implemented, then edit the HTML before it can be cached. So, the page should be cached on the second visit.

Is there a built-in feature or specific hook in WP Performance Score Booster that supports this functionality, and can be controlled through PHP?

I am considering a custom implementation using WordPress hooks. Here’s a brief overview of my approach:

// Function to update a custom field when a post or page is saved

function update_last_modified_meta($post_id) {

    update_post_meta($post_id, '_last_modified_time', current_time('mysql'));

}

add_action('save_post', 'update_last_modified_meta');

// Function to control caching based on the last modified time

function custom_per_page_cache_control() {

    if (is_single() || is_page()) {

        global $post;

        $stored_last_modified = get_post_meta($post->ID, '_last_modified_time', true);

        if ($post->post_modified !== $stored_last_modified) {

            // Send headers to prevent caching

            header("Cache-Control: no-cache, must-revalidate, max-age=0");

            header("Pragma: no-cache");

            header("Expires: Wed, 11 Jan 1984 05:00:00 GMT");

            update_post_meta($post->ID, '_last_modified_time', $post->post_modified);

        }

    }

}

add_action('template_redirect', 'custom_per_page_cache_control');

Is this approach is compatible with your plugin? Is there a solution specific to your plugin?

Any recommendations or best practices for implementing this would be greatly appreciated.

Thank you,

Jovan
