Preload your sitemap URLs into multiple Cloudflare edge locations using proxies and a custom Cloudflare Worker.

== Description ==

Super Preloader for Cloudflare helps you warm your site's edge cache across multiple Cloudflare nodes using proxies and a Worker URL. Perfect for globally distributed cache coverage.

== Installation ==

1. Upload the plugin folder to `/wp-content/plugins/`
2. Activate via the Plugins menu in WordPress
3. Go to **Settings → Super Preloader** to configure your Worker, Proxy list, and Sitemap.

== Getting Started ==

This plugin helps warm up Cloudflare edge caches by preloading your public URLs using a Worker script and optional rotating proxies. It helps reduce time-to-first-byte (TTFB) and improve real user performance metrics by ensuring content is already cached near your visitors.

Normally, Cloudflare only populates its edge cache in a specific location when a visitor from that region requests the page. This means content may be slow for first-time visitors in other geographic regions. By sending preload requests from various IP locations, the plugin helps increase Cloudflare cache hit rates across multiple edges.

It works best when used together with a caching plugin like [Super Page Cache](https://wordpress.org/plugins/wp-cloudflare-page-cache/), since Cloudflare does not cache HTML responses by default—only static assets like images, CSS, and JS. This can lead to better scores in Core Web Vitals—especially the Largest Contentful Paint (LCP)—which is a key factor in SEO and user experience.

To get started, follow the detailed instructions in our **How to Use** section below.  
Recommended steps:

1. Create and deploy your Cloudflare Worker URL  
2. Get your Webshare proxies download link  
3. Create your sitemap using Yoast SEO, RankMath SEO, or a similar plugin  
4. Start preloading

== Frequently Asked Questions ==

= What do I need to use this plugin? =

You need a Cloudflare Worker URL (required) and optionally Webshare.io proxies for better global coverage. The plugin provides the Worker script code to deploy to your Cloudflare account.

= Do I need a caching plugin? =

It's highly recommended. Cloudflare only caches static files by default, not HTML pages. Use it with Super Page Cache or similar plugins for best results.

= How does this improve my site performance? =

It pre-warms Cloudflare's edge caches globally, reducing Time to First Byte (TTFB) and improving Core Web Vitals scores. Users worldwide get faster page loads instead of slow "cache miss" responses.

== Screenshots ==
