 * Hi, I have two questions.
 * 1. Is there any option to preload pages and posts in Cloudflare PoPs using the
   preloader option inside the plugin? Or is it just for preloading cache on the
   origin server.
 * 2. Can you please tell what are the values for the following two and what they
   mean:
 * x-wp-cf-super-cache:
    x-wp-cf-super-cache-active

 * Hi [@amayahb5](https://wordpress.org/support/users/amayahb5/),
    The preloader
   system is technically supposed to cache content on CF edge as well as the origin
   server fallback cache. Our preloader uses cURL to preload pages/posts. Now the
   problem is that most of the times when Cloudflare sees a request is coming via
   cURL instead of an actual browser, it doesn’t cache the content in its edge server.
   This is something we can’t do anything about and this is a why the fallback cache
   will save you when the first request will come as then the fallback cache can
   instantly provide the HTML and then CF edge will cache it.
 * The `x-wp-cf-super-cache` & `x-wp-cf-super-cache-active` are some internal headers
   used by the plugin in order to understand whether or not to cache that page if
   you have manually excluded that page from being cached etc. This is something
   you don’t have to worry about thinking as this is purely used by the plugin internally.

 * Hi [@isaumya](https://wordpress.org/support/users/isaumya/),
 * I am very interested about your opinion:
 * >  Now the problem is that most of the times when Cloudflare sees a request is
   > coming via cURL instead of an actual browser, it doesn’t cache the content 
   > in its edge server.
 * , because I have never encountered a problem like this.
 * I tries many different kinds of curls, with user-agent, without user-agent, bash
   curl, php curl, python requests, …
    but every time cloudflare successfully cached
   ALL the pages in my website.
 * Can you please tell me more details about this? If I can reproduce it, maybe 
   I can understand better about cloudflare and improve my preloader script 🙂

 * Hi [@powercliff](https://wordpress.org/support/users/powercliff/),
    As you have
   stated, it is not always, but we have seen this happen multiple times across 
   the website. It’s totally random, sometimes CF caches a request invoked by curl
   and sometimes it doesn’t.

 * Thanks for your reply, I will observe my cache status more carefully from now
   on.
