If you omit the constant or set it to an empty value, cookies will belong … Read more
You should be loading jQuery with wp_enqueue_script(‘jquery’) – that way, you won’t end up with multiple instances if plugins try to load it too. To use Google CDN, place this in your functions.php; wp_deregister_script( ‘jquery’ ); wp_register_script( ‘jquery’, ‘https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js’, null, // Dependencies – none null // Version – use null to prevent WP adding version … Read more
The plugin works fine; alternative you can use a own function to replace the bloginf() to your CDN-Url; Example: replace the url in content: // replace content for CDN if ( !function_exists(‘fb_add_static_content_url’) ) { function fb_add_static_content_url($content) { if ( is_admin() ) // eigentlich überflüssig return $content; $wpurl = get_bloginfo(‘wpurl’); $search = array( $wpurl . ‘/wp-content/images/’, … Read more
The W3 Total Cache plugin changes the URL of various files in /w3-total-cache/lib/W3/Plugin/Cdn.php in the function *ob_callback*. It uses a series of callbacks to modify an output buffer.

If use a caching plugin like wp-supercache, or w3 total cache, they integrate with CDNs like Cloudfront to … Read more
The accepted answer is completely wrong. I suspect a gross misunderstanding of the OP’S question, since anyone with even a little experience with programming will never recommend something like “cache your own copy of the script, and perform get_url calls every 20 minutes”. @Paul G. says there is no point in loading from the CDN … Read more

Distributions can be created from existing S3 buckets, and when a file is requested from it’s CloudFront URL it is either served from the nearest edge locations’s cache or fetched from S3 and cached. Plugins My CDN – handles URL rewriting of JS, … Read more
You need to either Version your files (by calling it style.css?ver=xxx.xxx) and making sure your CloudFront distribution has “Forward Query strings” turned on. This is the better option, as it means that all you need to do is increment the number in the query string and CloudFront will fetch this file automatically. Manually invalidate your … Read more
The problem is that I’m pretty sure it’s impossible to check if CSS is effectively added to a page via PHP: CSS is parsed by the browser, so client side, and has completely no effect on server side. Of course, in PHP it’s possible to check if CDN is responsive or not… Option 1 Send … Read more
