Faster pages with page caching
Page Cache stores finished pages so they load instantly, and clears the cache by itself when something changes. Pro preloads the pages in the background and makes the files smaller.
In WordPress the plugin is called Datoden Page Cache – in the DT-addons menu it is listed as DT-cache.
DT-cache saves every page as a finished HTML file the first time it is visited. The next visitor gets that file straight away – on Apache and LiteSpeed the server sends it through .htaccess without starting WordPress, and on other servers (for example Nginx) the plugin sends it before the rest of WordPress loads. The cache empties itself when you change something, and logged-in users always see the live website.
Under DT-addons → DT-cache you turn on Save the pages and choose how long a page is kept – from 1 hour to 1 week, or Until something changes. Search, 404, password-protected pages, previews and the shop cart and checkout are never saved.
The cache is emptied automatically when a page, post, menu, widget, the Customizer, the theme or a plugin changes. Other DT plugins also empty it when they change something on the pages.
In the Never save these pages field you enter one address per line. /page/ means just that page, /page/* everything that starts with it, and *word* every address containing the word.
The card The cache now shows how many pages are saved, how much space they take and when the cache was last emptied. Check the front page tells you whether the page came straight from the server, through the plugin or not from the cache – and if not, why.
When you are logged in, the admin bar has a DT-cache menu with Empty all cache and, while you are looking at a page, Empty this page. The Empty the cache button is also on the settings page.
If WP Fastest Cache is on the website, the card Move from WP Fastest Cache appears. One click takes over its settings and excluded pages, turns it off and removes its cache and .htaccess rules.
After the cache is emptied, the front page, pages, posts and categories – whichever you tick – are visited in the background so no visitor has to wait. With DT-language every language domain gets its own cache, and preloading covers every language.
The Faster pages card has switches for Smaller HTML, Smaller CSS, Smaller JavaScript, Compress (gzip), Browser cache and Without the emoji script. With the browser cache, images, fonts, CSS and JavaScript are kept in the visitor's browser for four months. Here you also find Own cache for mobiles, which is only needed if the theme sends different HTML to mobiles.
Everything without a Pro label works for free. What is marked Pro is included in the Pro version.
After installing – how to set up Page Cache.
Go to DT-addons → DT-cache in the WordPress menu, or click Settings next to the plugin under Plugins.
Switch it on and choose under A page is kept for how long pages should stay in the cache – 24 hours is the default. Changes are saved automatically.
List any pages that must always be shown live, such as member pages, under Never save these pages.
Click Check the front page in The cache now card. The answer shows whether the front page is served from the cache, and what is stopping it if not.
Pro builds on the free version – it stays as the base, with all your settings, and Pro adds the rest.
Everything in the free version, plus:
Choose how many websites and how you want to buy. Prices exclude VAT – VAT is calculated at checkout.
The licence follows your Datoden account – no key to paste.
The purchase is saved on your Datoden account as soon as the payment has gone through.
Get the Pro plugin under My account → My purchases → Licences.
Drop the zip file on Website Guard. Pro is added on top of the free version – everything you have done stays.
Connect the website in Website Guard. The Pro updates then arrive as ordinary WordPress updates.
No. Logged-in users and commenters always get the live website, so you see your changes right away.
Yes. If the server does not read .htaccess, the plugin sends the saved pages itself, almost as fast. Gzip and browser caching in Pro do need .htaccess.
The answer gives the reason – for example that the front page redirects, that a plugin sets a cookie or marks the page as not cacheable, or that another cache sent the page.
No. DT-cache waits until WP Fastest Cache is turned off, because two page caches at once can give visitors the wrong pages. Use Move from WP Fastest Cache to switch.
In wp-content/cache/dt-cache/, with a folder per domain and address.
Nothing stops working. A purchase never runs out, and when a subscription ends the plugins keep every function – only the updates from Datoden stop.
The first number in the version. A purchase includes every update in that major version, for example all 1.x versions. A new major version (2.0) comes about once a year with clearly new features and comes at a discount as an upgrade. A subscription always includes it.
Websites connected to your Datoden account with a Pro plugin switched on, in the order they were connected. Disconnect a website in My websites to move the licence to another.
No. The website is connected to your Datoden account with Website Guard, and Datoden knows which updates your licences include.
Yes. Deactivate Pro – the free version keeps running with the same settings. Functions that only exist in Pro stop, but nothing is deleted.
Yes. Pro is an add-on: the free version stays installed and active as the base and is updated from WordPress.org as usual, and Pro adds the Pro features on top. On WordPress.org the free versions are called Datoden …, for example Datoden Page Cache.
Prices exclude VAT. VAT is calculated at checkout from your country. Companies in other EU countries can enter their VAT number.
Your licences, websites and downloads are under My account → My purchases → Licences.
