Frequently Asked Questions

Common questions about JTZL's In-Browser Cache

Most WordPress caching plugins focus on server-side caching, which reduces server load but doesn't help after content is delivered to the browser. In-Browser Cache operates entirely on the client-side, using modern browser capabilities to cache assets directly in the user's browser, reducing network requests and improving page load times on repeat visits.

Yes! In-Browser Cache complements server-side caching plugins. You can use both together for maximum performance benefits.

The plugin requires browsers that support Service Workers. This includes all modern browsers (Chrome, Firefox, Safari, Edge), but not older browsers like Internet Explorer. On unsupported browsers, the plugin gracefully degrades - your site will function normally, just without the caching benefits.

Yes, Service Workers only work on secure origins (HTTPS). This is a security requirement imposed by browsers, not a limitation of the plugin.

No, this plugin requires WordPress to be installed at the root of your domain (e.g., https://example.com/) and will not work properly if WordPress is installed in a subdirectory (e.g., https://example.com/blog/). This limitation exists because Service Workers have a scope restriction - they can only control pages within their own directory and subdirectories. Since the service worker is served from the root path (/service-worker.js), it can only cache resources for the entire domain when WordPress is at the root level. If your WordPress installation is in a subdirectory, the plugin will appear to install successfully but caching will not function properly.

No, the plugin is designed with performance in mind. The service worker registration is asynchronous and doesn't block page rendering. The caching itself improves performance by reducing network requests on subsequent page loads.

You can clear the cache from the plugin settings page by clicking the "Clear Cache" button. This sends a message to the service worker to delete all cached assets.

Currently, the plugin uses predefined rules based on file types and URL patterns. Custom exclusion rules will be added in a future update.

The metrics are collected directly from the browser and represent actual cache hits, misses, and bandwidth savings. However, they rely on the browser reporting accurate content-length headers, which may not always be available.

By default, the plugin disables caching for logged-in users to ensure GDPR compliance and protect user privacy. When users are authenticated, their browsing patterns and personal data should not be stored in browser caches without explicit consent. You can disable this feature in the plugin settings, but it's recommended to keep it enabled for privacy compliance.
