Flexa Cache is a full-featured WordPress page-cache and front-end optimization plugin. It installs a self-contained advanced-cache.php drop-in that serves compressed static HTML files before WordPress even loads — the same technique used by WP Fastest Cache and W3 Total Cache — giving you maximum TTFB improvement on both Apache and nginx hosts.
Page Cache
Static HTML cache served by a pre-WordPress drop-in (no PHP/MySQL on cache hits)
Gzip pre-compressed .gz files served natively
Separate mobile cache variant (index-mobile.html) when Mobile Theme is enabled
Smart invalidation: purge on new post, updated post, comments, theme/menu/widget changes, and WooCommerce product/stock updates
Per-URL cache purge from the admin UI, WP-CLI, or REST API
Cache preloader via Action Scheduler (or WP-Cron fallback) with start/cancel/status controls
Widget output cache with O(1) versioned-key invalidation
Front-End Optimization
Minify HTML (whitespace collapse) and Minify HTML Plus (inline CSS/JS trim)
Minify CSS and Minify CSS Plus (deeper punctuation squeeze)
Combine CSS — adjacency-only buffer fusion preserving cascade order
Combine JS / Combine JS Plus — concatenate header and footer scripts
Gzip — mod_deflate .htaccess block for dynamic (non-cached) responses
Browser Caching — Expires/Cache-Control .htaccess block
Disable Emojis — remove WordPress emoji scripts, styles, and DNS prefetch
Lazy Load — native loading="lazy" + decoding="async" on images and iframes
Render Blocking JS — add defer to render-blocking scripts
Google Fonts Async — rewrite Google Fonts to preload + onload swap with
