This is a really good helper plugin. Thanks so much for the development. The only thing that doesn’t work is the activation of the plugin in a XAMPP environment. I think I would have to dig deeper into the code, to see, what the error with XAMPP meant.. But anyways.. on my shared hosting it worked out of the box and is a very helpfull utility. If I find the time, maybe I’ll fork it 🙂
Thanks again for this masterpiece! Love it.

Perfect plugin, not much to change. Litespeed Cache is pretty bad without this, and incredible when paired with this. Also, I like it much more than even the official Litespeed crawler.

I have been looking for a plugin like this for a long time. With Redis full page caching, they are only added to the cache on first load and then dropped after 4 hours in the cache. This is a really nicely made plugin that will preload these files into cache at regular intervals. It’s an amazing plugin.

I waisted so much time with other «top» plugins trying to fix preloading cache and then this plugin shows up and simply did the job. Masterful work! Thanks

This is a well thought-out plugin.
A notable feature is that the log shows these three headers: cf-cache-status, x-cache and X-WP-Super-Cache. Which means you’ll know at one glance the status of Cloudflare’s edge cache, httpd’s mod_cache disk cache, and, I suppose, the WP Super Cache plugin’s less efficient disk cache if that’s what you’re using.

Thank you for this plugin.
It is a lifesaver, when you need a reliable cache warming tool. In my installation the standard preload of WP Rocket didn’t work as expected. I tried to find a solution for months.
Cache warmer now reliable preloads all given sitemaps in a defined interval.
