<p>Are you a frontend developer? Do you want to clear browser cache for all users? Just activate this plugin and show your work!</p>
<p>Prevent Browser Caching allows you to update the assets version of all CSS and JS files automatically or manually in one click.</p>
<p>Now you can show the latest changes on the site without asking the client to clear the cache.</p>
<h4>How it works?</h4>
<p>Usually, WordPress loads assets using query param “ver” in the URL (e.g., style.css?ver=4.9.6). It allows browsers to cache these files until the parameter will not be updated.</p>
<p>To prevent caching of CSS and JS files, this plugin adds a unique number (e.g., 1526905286) to the “ver” parameter (e.g., style.css?ver=4.9.6.1526905286) for all links, loaded using wp_enqueue_style and wp_enqueue_script functions.</p>
<h4>For developers</h4>
<p>By default, this plugin updates all assets files every time a user loads a page and adds options in the admin panel (Settings -> Prevent Browser Caching) which allows you to configure updating of these files.</p>
<p>But you can also set the version of CSS and JS files programmatically.</p>
<p>Just insert this code in functions.php file of your theme and change the value of assets_version when you need to update assets:</p>
<pre><code>prevent_browser_caching( array( 
    'assets_version' => '123' 
) );
</code></pre>


Prevent Browser Caching

I just want to thank the developer for this super useful plugin, it works wonderfully well, great job.

Thank you

Updates the assets version of all CSS and JS files. Shows the latest changes on the site without asking the client to clear browser cache.

<p>DietPress puts your WordPress on a diet and speeds it up. It pairs a complete set of performance optimizations (the ones that used to ship in “Zero Config Performance Optimization”) with a clean, risk-based interface to disable the WordPress features you do not use. Everything is configurable, and the performance optimizations are already on by default, so you can simply activate and enjoy a faster site, or fine-tune every detail.</p>
<blockquote>
<p><strong>Coming from “Zero Config Performance Optimization”?</strong> This is the same plugin, now called DietPress and fully configurable. All your previous optimizations stay active by default; you just gained a settings page and a whole new set of WordPress-diet options.</p>
</blockquote>
<p>By default WordPress loads functions, services and scripts that most sites do not need. They slow down loading times and consume hosting resources. DietPress lets you trim that fat and apply battle-tested performance tweaks, with a clear description of what each option does and what might break, organized by risk level so you always know what is safe.</p>
<h3>TWO THINGS IN ONE PLUGIN</h3>
<p><strong>1. Performance optimizations (on by default)</strong></p>
<ul>
<li>Automatic Critical CSS inlined in the head (optional experimental deferral of non-critical CSS)</li>
<li>JavaScript defer parsing with smart dependency handling</li>
<li>Image loading attributes safety net: lazy loading, decoding=async and fetchpriority for images that bypass core</li>
<li>Automatic image dimensions for better CLS scores (including picture elements)</li>
<li>Resource hints: preconnect and DNS prefetch for common third-party origins</li>
<li>Theme stylesheet, critical fonts and logo preloading for a faster LCP</li>
<li>Google Fonts display=swap</li>
<li>RSS feed optimization (cache headers and item limit)</li>
<li>Server rules in .htaccess: browser caching, GZIP and Brotli compression, immutable cache headers, CORS for fonts and keep-alive (master switch plus per-feature toggles)</li>
<li>Database maintenance: daily expired-transient cleanup and safe query optimizations</li>
</ul>
<p><strong>2. Put WordPress on a diet (risk-based, opt-in)</strong></p>
<ul>
<li><strong>Light</strong> (safe for any site): emojis, RSD/WLW tags, shortlinks, self-pingbacks, comment pagination, admin email check, and more</li>
<li><strong>Moderate</strong> (evaluate first): oEmbed, jQuery Migrate, Dashicons on the frontend, Global Styles and Duotone, remote block patterns, avatars and Gravatar, comment threading, and more</li>
<li><strong>Strict</strong> (site-specific): granular RSS feed control, Heartbeat API mode, post revisions and autosave, disable comments, XML sitemap, native lazy loading/fetchpriority, content types, and more</li>
<li><strong>Widgets</strong>: dashboard widgets (including third-party ones from Yoast, WooCommerce, Elementor, Jetpack, Wordfence, Rank Math, Gravity Forms), classic sidebar widgets, block-editor widgets and the Customizer</li>
</ul>
<h3>SCALE, PROFILES AND ANALYZER</h3>
<ul>
<li>Savings indicator: HTTP requests removed, CSS/JS saved and active optimizations at a glance</li>
<li>Quick profiles: Personal Blog, WooCommerce Store, Landing Page and Maximum Cleanup</li>
<li>Site analyzer: personalized recommendations based on your active plugins and content</li>
<li>Import and export your whole configuration as a JSON file</li>
</ul>
<h3>COMPATIBILITY AND EXTENSIBILITY</h3>
<p>The plugin includes filters for developers:</p>
<ul>
<li><code>dietpress_critical_css</code> – Customize the inline critical CSS</li>
<li><code>dietpress_critical_css_handles</code> – Define which CSS handles are critical</li>
<li><code>dietpress_skip_defer_script_handles</code> – Opt scripts out of the JavaScript defer</li>
<li><code>dietpress_skip_defer_style_handles</code> – Opt stylesheets out of the CSS deferral</li>
<li><code>dietpress_preconnect_hints</code> – Customize preconnect origins</li>
<li><code>dietpress_dns_prefetch_domains</code> – Customize DNS prefetch domains</li>
<li><code>dietpress_critical_fonts</code> – Define critical fonts to preload</li>
</ul>
<p><strong>Compatible with:</strong></p>
<ul>
<li>Well-coded themes and page builders (Divi, Elementor, Beaver Builder, Gutenberg)</li>
<li>Cache plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, etc.)</li>
<li>Security plugins (DietPress focuses on performance and deliberately leaves security to them; we recommend our free Vigilant)</li>
<li>CDNs (Cloudflare, StackPath, KeyCDN, etc.) thanks to CORS and Vary headers</li>
<li>WordPress Multisite</li>
</ul>
<h3>HOW TO VERIFY THE OPTIMIZATIONS</h3>
<ul>
<li><strong>Cache rules:</strong> check your <code>.htaccess</code> for a block marked <code># BEGIN DietPress</code> with <code>immutable</code> Cache-Control headers</li>
<li><strong>Logo preload:</strong> view page source and look for <code><link rel="preload" ... fetchpriority="high"></code> pointing to your logo</li>
<li><strong>Critical CSS:</strong> view source and look for <code><style id="core-diet-critical-css"></code> in the head</li>
<li><strong>Compression:</strong> test at <a href="https://www.giftofspeed.com/gzip-test/" rel="nofollow ugc">giftofspeed.com/gzip-test</a></li>
</ul>
<p>Always measure with tools like Google PageSpeed, GTMetrix or WebPageTest, and run each test at least twice to account for caching.</p>
