Browser and CDN Caching Headers for Visitors
Sends Cache-Control headers on public pages for logged-out visitors, so a CDN or proxy can cache them for a few minutes.
Snippet Library
WordPress code snippets, ready to use
3,040 free snippets from the WPIDE team and the community. Copy the code, or add any snippet to your site in one click with WPIDE.
Browser and CDN Caching for Feeds and Sitemaps
Sends cache headers on RSS feeds and XML sitemaps so feed readers, crawlers and CDNs can reuse them for an hour instead of making WordPress rebuild them on every request.
Cache-Busting Versions Based on File Changes
Replaces the version number on your theme's and plugins' CSS and JavaScript URLs with the file's last-modified time, so browsers and CDNs cache files for a long time but always fetch a fresh copy right after you change one.
Disable Responsive Image srcset
Stops WordPress from adding srcset and sizes attributes to images, for sites where an image CDN already serves the right size.
Keep Some Images Off Jetpack's Image CDN
Serves images from your own server instead of Jetpack's Site Accelerator CDN when their URL contains a pattern you choose, for example SVGs, signed URLs or a specific folder.
Preload Header for Your Theme Stylesheet
Sends an HTTP Link preload header for your theme's main stylesheet, so browsers, and CDNs that support Early Hints, start downloading the CSS before the HTML has even arrived.
Serve Media and Static Files From a CDN Domain
Rewrites the URLs of your uploads, theme and plugin files to a CDN or pull-zone domain you set, so images, CSS and JavaScript are delivered from the CDN while pages are still served by your site.
Skip W3 Total Cache on Chosen Pages
Tells W3 Total Cache not to page-cache, minify or serve from CDN the pages you choose, using its documented DONOTCACHEPAGE-style constants.
Subresource Integrity for Scripts and Styles From CDNs
Adds integrity and crossorigin attributes to the CDN-hosted scripts and stylesheets you list, so browsers refuse to run them if the CDN copy is ever tampered with.
