I use W3TC, so these are approaches that I can come up with it for it: Fragment caching to exclude that part of page, will reduce cache effectiveness overall. Identify page with switched stylesheet by query argument, disable caching of such pages. Identify page with switched stylesheet by URL endpoint, disable caching of such by … Read more
You should not cache anything in the admin so your examples are correct. A typical nginx reverse proxy cache is set to ignore wp\-.*\.php|wp\-admin Another option is to not cache logged in users by checking the wp cookies, but you probably don’t have that level of control. ps. It is highly advisable you test this … Read more
I would recommend W3 Total Cache. It optimizes over several different aspects of the site (HTML, database, etc.) and I haven’t ran into any issues with it.
If you have access to your request header you can add the line. Cache-Control: private or Cache-Control: no-cache. This will force well-behaved hosts to send you fresh results.
Use this instead of the line in wich you define $days (your second line): $transient = get_transient( ‘your_transient_key’ ); if( !$transient ): $days = file_get_contents( ‘json_file’ ); set_transient( ‘your_transient_key’, $days, DAY_IN_SECONDS*7 ); else: $days = $transient; endif; $days = json_decode( $days ); … May be a bit rough but you get the idea.
It has this natively: Performance > Page Cache > General > Don’t cache pages for logged in users You can always check if you are seeing cached page by looking at page source, W3 outputs status (commented out) at end of page.
Use null as $ver param: wp_deregister_script( ‘jquery’ ); wp_register_script( ‘jquery’, ‘https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js’, false, null); wp_enqueue_script(‘jquery’); Output: <script type=”text/javascript” src=”https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js”></script>
You could delete an existing cache for your option before you call get_option(): $GLOBALS[‘wp_object_cache’]->delete( ‘your_option_name’, ‘options’ ); $value = get_option( ‘your_option_name’ );
The wp_cache_*() functions are non-persistent caches which means that they only last during the current page request. This would be beneficial if you’re requesting the same information multiple times during page load. For example, if you’re showing recent posts in the header, content section, and sidebar ( calling the same code 3 times to retrieve … Read more
I’m not a friend of link only answers, but as I can’t bind the whole source code + explanation in here, I’ll just leave a link to @Rarst Fragment Cache Plugin.
