原文外掛簡介
Speedora is a free, all-in-one speed plugin. It caches pages, minifies HTML/CSS/JS, lazy-loads media, converts images to WebP, and removes unused WordPress baggage. Settings are grouped by feature, and child options stay locked until their parent is enabled.
Do not run Speedora page cache together with another page-cache plugin (WP Super Cache, W3 Total Cache, LiteSpeed Cache, and similar). Use one page cache at a time.
Page caching
File-based full-page cache for guests (optional cache for logged-in users)
Separate cache files for mobile/desktop and for Polylang/WPML languages
Cache lifetime, automatic purge on update, and smart purge of the changed URL
Cache preload for homepage, sitemap URLs, and newly published posts
Skip URLs with query strings (tracking parameters such as utm_source are allowed)
Never-cache list (path fragments such as /cart/)
WooCommerce: do not cache cart, checkout, or account pages
Cache hits send the X-Speedora-Cache header
Browser cache and gzip
Cache-Control, ETag, and Last-Modified on HTML when page cache is off
Apache .htaccess expires for CSS, JS, images, and fonts
Apache gzip/deflate for HTML, CSS, JS, and SVG
Rules are written with WordPress insert_with_markers (marker: Speedora)

Minify local CSS and JS into copies under uploads (skips wp-includes)
