Don’t cache Request URI with specific params

Hi @kleindberg

Thank you for using our plugin!

At this point there is only one way to avoid caching urls with specific parameters and that is by creating a mu-plugin which uses the filter wp_rest_cache/skip_caching. It has to be a mu-plugin because of the way our plugin works, the caching mechanism is also started from a mu-plugin. So if you would use a normal plugin your code would be executed too late and would have no effect.

Now how to do it exactly: as said, you need to create a mu-plugin. So create a file named skip_cache_for_search.php in wp-content/mu-plugins. The file can be any name, as long as it is alphabetically before wp-rest-cache.php. In this file you can put the following code:

<?php
add_filter( 'wp_rest_cache/skip_caching', 'wprc_skip_cache_for_search' );
function wprc_skip_cache_for_search( $skip ) {
	return isset( $_GET['search'] );
}

That is it, now all calls to the REST API which contain the search parameter will no longer be cached.

Thanks for such a quick response. It would be awesome to see paid PRO version of WP REST Cache optimized for WooCommerce API ??
