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

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. Compatible caching plugins tested with Content No Cache W3 Total Cache WP Fastest Cache WP Optimize Comet Cache Cache Enabler Hyper Cache WP Super Cache LiteSpeed Cache Speed Optmizer WPRocket All of those caching plugins are compatible with Content No Cache. If your favorite caching plugin is not compatible for any reason, let us know it Compatible CDNs Cloudflare BunnyCDN StackPath KeyCDN Fastly CloudFront Main features Ultralightweight plugin. 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.

THIS PLUGIN IS STILL EXPERIMENTAL – USE AT YOUR OWN RISK! The plugin is under development. Please try it and contact me if you encounter any bugs or have any questions or suggestions. If you want to help me develop this further send a pull request on GitHub. The plugin is not ready for production yet, but I will soon release version 0.1 that will be production ready. WP-PJAX – PJAX for WordPress Plugin. Makes your site faster and saves you a lot of bandwidth and CPU power by making your WordPress site PJAX powered! What is PJAX? PJAX is a technique that uses AJAX and PushState to deliver a faster browsing experience by only loading and updating parts of the page HTML each page load. PushState makes it possible to add real permalinks, page titles, and a working back button so that your visitors won’t be able to tell the difference between PJAX page load and ordinary full page loads, except for the increased speed of course :). Why PJAX? It makes your site significantly faster in most cases and saves you both processing power and bandwidth! Features Speeds up any website. With the built in page cache enabled you can expect 10-50+% faster page loads. Supports 4 Levels of application cache! This plugin uses browser cache and page cache. It is also enabling reverse proxy(i.e. Varnish) cache by (optionally) striping sessions and cookies and it works very well with underlaying object and database cache using third party cache plugins such as W3 Total Cache (recommended). Works well with W3 Total Cache. Configurable. No need to dig into the code. You will still need basic knowledge about HTML and how WordPress works to make this plugin reach it’s full potential. Live notices with a report for every page load (Load time, page cache hit or miss, Reverse proxy/Varnish cache miss or hit etc – See screenshot). This is great for debugging and testing and is of course only visible for admins. Only a few changes in your theme and you are ready to go. Should not take more than 5 minutes and requires only basic knowledge. Browser support PJAX is not supported in Internet Explorer 9 and earlier(IE 10+ supports this), but the plugin handles this gracefully by falling back on regular page loads for unsupported browsers. Details on browser support Development All development of this plugin occurs on GitHub. Please help me develop this by forking and sending pull requests. Planned features / To-Do Better handling of menu active classes. Will probably use regex for this. Support for marking parent pages active would be nice but I don’t know any good ways to accomplish that. Better control over exceptions for when to disable PJAX, when you use Page cache, and when and what cookies and sessions that should be striped. Regex support will be added. Refresh cache on publish/update. Separate loading of sidebars with separate cache. Page loading notice / icon. This should also be customizable with css, text(localizable) and it should be possible to upload your own icon. Page cache prefetch needs to be revisited. WP-Cron is a bit tricky and its hard to handle timeouts gracefully and reliably cross different environments. Remove all debug code and general code cleanup. This will be finished before the 0.1 release. Add an optional menu to the admin bar for clearing cache(all and current page). Optimize execution flow for better performance Maybe: Better way to generate the configurable javascript. I think of two options for this, ether use wp_localize_script to inject variables into javascript or to generate a javascript with PHP file when settings are saved. Known issues The PJAX toggle checkbox does not work. $.pjax.disable() does not seam to work as it should. Maybe I need to set a cookie with AJAX to set this for the current user and then handle it on the server side. Development All development of this plugin occurs on GitHub.
