Trying to create a function to purge cache for few URLs

Hi, I’m using litespeed cache with Litespeed server and I tried to create a function like this one:

//Function to purge specific URLs
function purge_specific_urls() {
    // Liste des URLs à purger
    $urls_to_purge = array(
        'https://example.com/page1',
        'https://example.com/page2',
        // Add other URLs here
    );
    // Loop through each URL and purge the cache
    foreach ( $urls_to_purge as $url ) {
        LiteSpeed_Cache::purge_url( $url );
    }
}

But the command LiteSpeed_Cache::purge_url( $url ) not seems to works, is there a setting on the litespeed server that I need to do to make it work?

By the the command header(‘x-litespeed-purge:/****/’); is working but only for a URL

If you can help me with this, it will be great since I checked on many forums and found nothing to help me.

Thanks !
