Content No Cache | Serve uncached partial content even when you add it to a page that is fully cached. vs SQLite Object Cache

Normally, if a web page is served by the cache, its content will be always the same until the cache is deleted. By adding the content with the shortcode provided by Content No Cache, you will be able to show dynamic content even on pages served by cache. You don’t need this plugin to exclude the entire page from the cache. This plugin is to exclude a part of the page from the cache. It’s useful if you need to cache a page, but part of that page should not be cached. Imagine you have a page that has this content: Hello this is some text. Another line of text Another line of text Current day: Monday if that page is served by cache, the user will always see: Hello this is some text. Another line of text Another line of text Current day: Monday If you need that the last line of text is always updated, this plugin will help you. The entire page will be served by the cache, but the plugin will get the updated content that you need. How to show dynamic content with full page cache Install Content No Cache Create a new element “Content No Cache” Add to that element all the content that you want to exclude from the cache Copy the shortcode that you will see in the section “Shortcode”. It will look like [content_no_cache id=”3328″]. The parameter “id” is the ID of the content element (in this example 3328). Add the shortcode to the page where you want to display that content.

The few lines of code will run only where you add the shortcode. No jQuery, no JS libraries, only a couple of lines of pure JavaScript No database queries, no extra HTTP requests for external assets, no bloat With a few line of ultralight code you can fully cache the page even if you need dynamic content on that page It provides a shortcode, so you can add it everywhere, no matter the builder Tips to speed up the process to get the content Install Freesoul Deactivate Plugins Go to Freesoul Deactivate Plugins => Actions => Content No Cache Disable all the plugins that you don’t need to output the content Example You can see Content No Cache in action visiting the blog post Exclude specific content from being cached. You will see a number that is always different when you refresh the page. But the page is served by full page cache. In the example it’s just a number, but you can output whatever content you want. Possible conflicts Some plugins don’t load the shortcodes during ajax requests. Because Content No Cache retrieves the content through ajax, in those cases the content will not be displayed properly. If you have this kind of issue set the parameter request=”remote”. In this case the shortcode will look like [content_no_cache id=”3328″ request=”remote”] The plugin will retrieve the content in a different way that will be a little slower, but this will solve this kind of conflict.

A persistent object cache helps your site perform well. This one uses the widely available SQLite3 extension, and optionally the igbinary and APCu extensions to php. Many hosting services offer those extensions, and they are easy to install on a server you control. What is this about? It’s about making your site’s web server perform better. An object cache does that by reducing the workload on your MariaDB or MySQL database. This is not a page cache; these persistent objects go into a different kind of cache. These objects aren’t chunks of web pages ready for people to view in their browsers, they are data objects for use by the WordPress software. Caches are ubiquitous in computing, and WordPress has its own caching subsystem. Caches contain short-term copies of the results of expensive database lookups or computations, and allow software to use the copy rather than repeating the expensive operation. This plugin (like other object-caching plugins) extends WordPress’s caching subsystem to save those short-term copies from page view to page view. WordPress’s cache happens to be a memoization cache. Without a persistent object cache, every WordPress page view must use your MariaDB or MySQL database server to retrieve everything about your site. When a user requests a page, WordPress starts from scratch and loads everything it needs from your database server. Only then can it deliver content to your user. With a persistent object cache, WordPress immediately loads much of the information it needs. This lightens the load on your database server and delivers content to your users faster. Who should use this? If your site runs on a single web server machine, and that server provides the SQLite3 and igbinary extensions to php, this plugin will almost certainly make your site work faster. And if that server provides the APCu extension, this plugin uses it too. Some hosting providers offer redis cache servers. If your provider offers redis, it may be a good choice. You can use it via the Redis Object Cache plugin. Sites using redis have one SQL database and another non-SQL storage server: redis. Other hosting providers offer memcached, which has the Memcached Object Cache plugin. And some large multipurpose cache plugins, such as the LiteSpeed Cache, also offer object caching based on one of those cache server software packages. The cache-server approach to object caching comes into its own when you have multiple load-balanced web server machines handling your site. SQLite doesn’t work correctly in a multiple-web-server environment. But, for single-server site configurations, SQLite, possibly assisted by APCu, performs well. And the vast majority of sites are single-server. APCu APCu is an in-memory storage medium. It lets php programs, like WordPress, store data in shared memory so it’s very fast to retrieve when needed. If APCu is available on your host server, you can configure this plugin to use it. It reduces the typical cache lookup time to one-fifth or less of the SQLite lookup time, which is itself a few tens of microseconds. Performance counts, especially on busy web sites. Please look at Installation to learn how to configure this plugin to use APCu. The plugin works fast without it, and faster with it. WP-CLI: Even if APCu is in use, caching with SQLite is necessary when your web site uses WP-CLI, because WP-CLI programs do not have access to the APCu cache. This plugin writes all cached data both to APCu and to SQLite and makes sure the two are synchronized. WP-CLI You can control this plugin via WP-CLI once you activate it. Please type this command into your shell for details. wp help sqlite-object-cache Credits Thanks to Till Krüss. His Redis Object Cache plugin serves as a model for this one. And thanks to Ari Stathopoulos and Jonny Harris for reviewing this. Props to Matt Jones for finding and fixing a bug that appeared on a heavily loaded system. Thanks to Massimo Villa for testing help, and to nickchomey for a comprehensive code review. All defects are, of course, entirely the author’s responsibility. And thanks to Jetbrains for the use of their software development tools, especially PhpStorm. It’s hard to imagine how a plugin like this one could be developed without PhpStorm’s tools for exploring epic code bases like WordPress’s.
