Ignoring query strings

Hello,

I understand you’d like to configure WP-Optimize to ignore certain query parameters so that all visitors get served from the cache, irrespective of the query strings in the URL. You can indeed accomplish this by utilizing the available wpo_cache_ignore_query_variables filter hook.

Here’s how you can customize this hook to include specific query parameters that should be ignored by the cache:

function custom_wpo_cache_ignore_query_variables($exclude) {
    $new_variables = array('your_query_var1', 'your_query_var2'); 
    $exclude = array_merge($exclude, $new_variables);
    return $exclude;
}
add_filter('wpo_cache_ignore_query_variables', 'custom_wpo_cache_ignore_query_variables');

Please replace 'your_query_var1' and 'your_query_var2' with the actual query parameters you want WP-Optimize to ignore. Add this code to your theme’s functions.php file or a custom plugin.

This adjustment will ensure that these query parameters do not prevent pages from being served from cache, thereby potentially improving your site’s performance for users who visit your site via referral links that include these parameters.

Let us know if you have any further questions or need assistance. We’re here to help!

Hi wpmansour,

thanks for your super fast response! I’m having a hard time to make the snippet work though.
I added

function custom_wpo_cache_ignore_query_variables( $exclude ) {
    $new_variables = array('utm_source', 'utm_campaign', 'fbclid');
    $exclude = array_merge($exclude, $new_variables);
    return $exclude;
}
add_filter('wpo_cache_ignore_query_variables', 'custom_wpo_cache_ignore_query_variables');

to the Themes’ functions.php, flushed WPO-Cache and visited mydomain.com/?fbclid=1 in an Incognito Tab.

The result was (WP-Debug enabled):

<!-- WP Optimize page cache - https://getwpo.com - Page not served from cache because: In the settings, caching is disabled for matches for one of the current request's GET parameters -->

I then tried adding the Snippet via WPCode and via muplugin – with the same result. Changing the Theme to Twenty Twenty-Four didn’t help either.
So maybe i’m missing sth.? Any ideas why it’s not working?

Best regards!

I had the same result as OP:

Thank you for your patience. Here is an update regarding the issue with ignoring specific query parameters for caching.

This feature is not supported in the free version of WP-Optimize because advanced-cache.php is executed before MU-plugins are loaded. This prevents the necessary filters from being applied in time.

However, the premium version supports this functionality as it loads extensions with advanced-cache.php, ensuring that the filters are applied correctly.

Thank you for looking into into my issue and your detailed explanation! Will consider upgrading then.
