About

Website Cache warmer can be used to-pre warm your website's cache.

Most websites will clear your website's cache on content updates or even periodically. To test if a low cache hit ratio is caused by invalidated cache will cause pagespeed issues you could pre-warm the cache and measure the difference.

This plugin will let you pre-warm the cache of your site in the easiest way possible.

Since I do not want this plugin be be abused I have built in a 1-second default delay. This delay can be removed by adding the cache-warmer to your robots.txt and set the crawl-delay to 0. Instructions are shown in the plugin!

New in 1.1: optional settings to ignore pages by regex and the option to ignore query strings, smoother ux and the last 30 settings are now saved.

New in 1.2: the cache warmer will first clear the site's browser cache and search for a sitemap to seed the url list.
