Rebuild existing cache

    I really like the plugin. It is efficient and easy to use.

    I would like to know if it is possible to force the existing cache to refresh in place? (so create a new cache of whatever is already cached)

    The reason to do so instead of using the schedule delete of the entire cache is to avoid a user encountering a non-cached page and having to create the cache on page load. It is preferable for the system to prime the cache (taking however long it takes) so all user requests are fast.

    If not possible to do so for entire cache, is it possible to delete a specific page’s cache using a url parameter? I would then create a script that clears the cache for the page and immediately reloads the page. Not as good as option 1 (refresh cache on back-end), but still reduces likelihood of user getting an uncached page.

    if ( isset( $GLOBALS[‘wp_fastest_cache’] ) && method_exists( $GLOBALS[‘wp_fastest_cache’], ‘singleDeleteCache’ ) ) {
    $GLOBALS[‘wp_fastest_cache’]->singleDeleteCache(false, $post_ID);
    }

    Can you try it please?

    Emre, I thank you for the code. It works as intended.

    Is there a way to load a page into the cache as well?

    Something like:
    $GLOBALS[‘wp_fastest_cache’]->cachePost($post_ID);

    I stand corrected. While the code itself seems to do what it needs to, the browser does not load the updated content unless I clear the full cache.

    Am I missing something where I can instruct the cache to send the browser the updated data?

    I resolved the issue by creating a back-end shell script to remove the cached paged and then load them, essentially clearing the cache for each page.

    The bash script is a back-end process which I run under cron.

    The script iterates through the pages I want to refresh and performs the following actions:
    – Remove page: rm ~/www/wp-content/cache/all/<page name>
    – Forces a reload by reading the page: wget -qO- -T 30 https://www.<domain>.com/<page name> > /dev/null
