Test if fragment caching is working

December 19Hits:39

I had this fragment caching function added in the `function.php. it goes like this:

    function fragment_cache($key, $ttl, $function) {           if ( is_user_logged_in() ) {             call_user_func($function);             return;           }           $key = apply_filters('fragment_cache_prefix','fragment_cache_').$key;           $output = get_transient($key);           if ( empty($output) ) {             ob_start();             call_user_func($function);             $output = ob_get_clean();             set_transient($key, $output, $ttl);           }           echo $output;         }   

I'd called the function on my php files. How can i possibly test if the fragment cache is working?
