I don’t think that there is a way to do this. All that shortcode does is generating some HTML code and putting it as content. But… there is a workaround you can use. Your shortcode can generate only a placeholder for its content and then you can use AJAX to populate it with real content. … Read more
Page cache is the entire rendered html output for a page. It’s useful for serving static content like a WordPress post. Object cache is often the resource-heavy pieces that make up a page. For example, When you use WP_Query each result would be stored in object cache. This prevents WordPress from hitting the database every … Read more
Rather than incorporating dynamic content into cached pages, you are better off using AJAX to pull dynamic content onto those pages in the browser. In your news.php file, simply have an empty element that will contain the content. Better still, have it contain an AJAX spinner that indicates that content is coming. <div id=”late-load-news”> <img … Read more
The following script takes the url that was asked from the client. It checks whether there is a fresh version of a static HTML page on the cache and if yes, it servers that. If the file does not exist at all or the it is expired(I check its modification date) then the request is … Read more

This might not be quite effective, because you may want to test how caching works on development. However, I found (at least for me) testing in development to be useless since … Read more
It’s a great question, and one I’ve been a little confused by as well. The conclusion I’ve drawn is, it’s expensive to leave cache files for two reasons: If your site (or sites, in the case of a multisite installation) has/have a lot of pages, you can easily end up with thousands of cache files, … Read more
It did appear that the json wasn’t being cached by wp-super-cache, but we decided to take a different approach. By using the transient api, we were able to do a faux-cache on all json, and drastically reduce the taxing of the database. Then on the ajax side of things, we are caching the html that … Read more
Your solution with comment_author_proxyhash cookie will of course technically work – all caching plugins I know doesn’t analyze hash value and will just stop delivery of cached content based on comment_author_* cookie presense. Problem here is that page caching functionality is something websites really need and often page caching is configured exactly because naked WordPress … Read more
