Use the API to customize smart purging, customize cache rules, create cache varies, and make WP nonce cacheable, among other things. Privacy This plugin includes some suggested text that you can add to your site’s Privacy Policy via the Guide in the WordPress Privacy settings. For your own information: LiteSpeed Cache for WordPress potentially stores a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules. In addition to caching, our WordPress plugin has online features provided by QUIC.cloud for Image Optimization and Page Optimization services. When one of these optimizations is requested, data is transmitted to a remote QUIC.cloud server, processed, and then transmitted back for use on your site. QUIC.cloud keeps copies of that data for up to 7 days and then permanently deletes it. Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to LiteSpeed so that we may better provide technical support. None of these features collects any visitor data. Only server and site data are involved. QUIC.cloud CDN, if enabled, uses LSCache technology to access your site, and serve your content from remote global nodes. Your data is not accessed by QUIC.cloud employees in any way, except as necessary in providing maintenance or technical support. Please see the QUIC.cloud Privacy Policy for our complete Privacy/GDPR statement.

Speculative Loading
This plugin adds support for the Speculation Rules API, which allows defining rules by which certain URLs are dynamically prefetched or prerendered. This core Speculative Loading functionality was merged into WordPress 6.8, but it only prefetches with conservative eagerness by default. In contrast, this plugin defaults to prerendering with moderate eagerness (i.e. when interacting with a link), and it provides a user interface to customize the mode and eagerness via the “Speculative Loading” section on the Settings > Reading admin screen. By default, speculative loading is only enabled for logged-out users, since unauthenticated pages are typically only eligible for caching and so more efficient to prefetch/prerender. This means that sites with frequent logged-in users on the frontend—such as e-commerce, forums, or membership sites—will not benefit from the feature. If your server can handle the additional load (for example, with persistent object caching), you can opt in to enable speculative loading for all logged-in users or for administrators only. This setting exclusively affects frontend pages; admin screens are always excluded. A filter can be used to exclude certain URL paths from being eligible for prefetching and prerendering (see FAQ section). Alternatively, you can add the no-prerender CSS class to any link ( tag) that should not be prerendered. See FAQ for more information. Browser support The Speculation Rules API is a new web API, and the functionality used by the plugin is supported in Chromium-based browsers such as Chrome, Edge, or Opera using version 121 or above. Other browsers such as Safari and Firefox will ignore the functionality with no ill effects; they will simply not benefit from the speculative loading. Note that certain browser extensions may disable preloading by default. Browser support for the Speculation Rules API in general Information on document rules syntax support used by the plugin This plugin was formerly known as Speculation Rules.
