Each page load triggers a database query that reads all the options (from what I’m aware the option records are all auto-loaded). Anyway 317 K is not something you should worry about, but there are better ways to store your data, for example a simple text file that gets read trough ajax only when the … Read more
Caching shouldn’t affect Modernizr since it’s a client-side script and will run every time the page is visited. I haven’t used Headway but from what you describe it sounds like a server-side script in Headway is sniffing the browser and that’s the result being cached. Does that make sense?
The best way I can think of is to add a unique string to the end of the stylesheet include to get everything to update. For example, if you are including it in the header.php file: <link rel=”stylesheet” href=”https://wordpress.stackexchange.com/questions/62636/<?php echo get_stylesheet_uri(); ?><?php echo”?v=’. time(); ?>” /> Of course that will keep it from being cached… … Read more
In WordPress, the WP_Feed_Cache class uses the WP_Feed_Cache_Transient class to store the results into a transient. So, short answer, either in the database or in the Object Cache if you have a persistent object cache stored. If you need to cache something for a period of time, use a transient. http://codex.wordpress.org/Transients_API
Try using a caching plugin. There’s plenty available, the two most popular being WP Super Cache and W3 Total Cache. If you’re just starting out with caching, I’d recommend W3 Total Cache, as it is rather easy to set up and includes a lot of options. It’s even used by some of the bigger sites … Read more
I’ve experienced the same issue. I’m not 100% sure yet if this is helping because it’s an intermittent issue, but as noted on the plugin author’s docs, this is a potential new fix for the problem: <!– mfunc wp_nav_menu( $args ); –> <?php wp_nav_menu( $args ); ?> <!– /mfunc –> UPDATE As of version 2.3 … Read more
You can use following code to exclude page from caching. define(‘DONOTCACHEPAGE’, true); //Disables page caching for a given page. define(‘DONOTCACHEDB’, true); //Disables database caching for given page. define(‘DONOTMINIFY’, true); //Disables minify for a given page. define(‘DONOTCDN’, true); //Disables content delivery network for a given page. define(‘DONOTCACHCEOBJECT’, true); //Disables object cache for a given page and … Read more
This is a response to your second question — “Also, it looks like the main page of the site is not cached, while everything else is. Is there any way to deal with that?” In your backend, go to Settings -> WP Super Cache and select the Advanced tab. Look for the section titled Accepted … Read more
Figured it out. Looking at wp-comments-post.php there is a filter called comment_post_redirect which I used to check if the comment was approved and then added a query string to the URL. So easy. //A query string needs to be added when redirecting back to the post after a comment is posted and not approved. This … Read more
I am not completely sure what you are talking about so I will mention the possibilities that come to mind. Maybe this… // Keep track of the last query for debug.. $this->last_query = $query; http://core.trac.wordpress.org/browser/tags/3.5.2/wp-includes/wp-db.php#L1195 … is what you are talking about. If so, your code just runs the flush method which resets $wpdb properties … Read more
