Comet Cache Pro

Dynamic WordPress pages are rebuilt on the server for each request, which adds load when traffic grows. Comet Cache Pro stores static copies of your pages, posts, categories and tags and serves those copies instead. The plugin is built to be simple, with a short configuration process that does not call for technical expertise.

Once caching is running, the plugin watches for changes to posts, pages, themes, tags and users, then clears only the cache files that need it. You can set expiration times, exclude certain URLs and browsers, and connect a CDN. It fits single blogs, multisite setups, membership sites and community platforms, since it can also cache content for logged-in users.

Features

• Quick, simple setup: The configuration is short and well documented, so you can get page caching running without technical expertise or a long setup process.
• Full page caching: Pages, posts, categories and tags are cached as static files, which lowers server load and speeds up page generation.
• Automatic cache clearing: The plugin monitors changes to posts, pages, themes, tags and users, then selectively clears only the cache files affected so your site stays current.
• Browser caching: Visitors' browsers can cache content too, giving a second layer of caching that speeds up repeat visits without hitting your server.
• Feed and 404 caching: RSS, RDF and Atom feeds can be cached, and so can Not Found pages, which reduces strain from bots or invalid URLs.
• Custom expiration and exclusions: Set cache expiration to match how often your site updates, and use URL and user-agent exclusion patterns to improve compatibility with themes, plugins and mobile devices.
• CDN and logged-in user support: Connect a Content Delivery Network to distribute cached content, and cache pages for logged-in users on membership sites and community platforms.
• AJAX clear button and compression: Clear the cache on demand with an AJAX button that avoids a full page reload, and compress cached HTML output to reduce page size.

Best for

• WordPress site owners who want simple page caching
• Membership and community sites with logged-in users
