Imagine a high traffic website that needs post views as an algorithm to display posts on the homepage. 
This website also uses <a href="https://wordpress.org/plugins/vcaching/" rel="ugc">Varnish Caching</a>. So we need an AJAX based post views counter. 
Now imagine a minimum 5000 concurrent users browsing the website, so we can’t use the default “AJAX in Plugins” as live updates on the backend using update_post_meta will be very painful for the backend.
So what can we do ?
What if all these post views counts will be done in memory using Redis ? 
Then we run a cornjob using WP-CLI to sync the post views count in Redis to the WordPress database.
Redis Post Views was born.

FlynCache Purge is a professional, lightweight WordPress plugin that automatically detects your server’s cache configuration and intelligently manages cache purging across multiple cache layers.

<li>Nginx FastCGI Cache Purge — Purges Nginx FastCGI cache by file removal, supporting multiple directory structures (Webinoly, EasyEngine, ServerPilot, and custom configs)</li>
<li>Redis Object Cache Purge — Connects to Redis via phpredis extension for full database flush or selective key purge</li>
<li>LiteSpeed Cache Purge — Integrates with LSCWP plugin API, LiteSpeed purge headers, and filesystem-based cache clearing</li>

<h3>External Services</h3>
This plugin optionally connects to the following external services. These services are only used when you explicitly enable and configure them in the plugin settings. No data is sent unless you opt in.
Cloudflare API v4
This service is used to purge Cloudflare CDN cache when you enable the Cloudflare cache purge feature. It is needed to send cache purge requests for your Cloudflare zones.
<ul>
<li>What data is sent: Your Cloudflare API token and Zone ID (stored in your WordPress database) are used to authenticate purge requests. No user data or content data is transmitted.</li>
<li>When data is sent: Only when you manually purge cache or when auto-purge triggers and Cloudflare is enabled.</li>
<li>Where data is sent: https://api.cloudflare.com/client/v4/</li>
<li>Terms of Service: https://www.cloudflare.com/terms/</li>
<li>Privacy Policy: https://www.cloudflare.com/privacypolicy/</li>
</ul>
LiteSpeed Admin API (optional)
If configured, the plugin can send purge requests to a LiteSpeed Admin API endpoint. This is entirely optional and only used if you provide the Admin URL and API key in settings.
<h3>Why FlynCache Purge?</h3>
Managing cache across multiple layers (server cache, object cache, CDN cache) is complex. Each cache has its own purge method, API, and configuration. FlynCache Purge unifies all cache management into a single, intelligent interface that auto-detects your setup and handles purging automatically — so you never have to worry about stale content again.
<h3>Supported Cache Types</h3>
<ul>
<li>Nginx FastCGI Cache — File-based cache used by Nginx with PHP-FPM (supports Webinoly, EasyEngine, ServerPilot, and custom configs)</li>
<li>Redis Object Cache — Via phpredis extension, supports host/port/unix socket, authentication, and database selection</li>
<li>LiteSpeed Cache — Server-level cache + LSCWP plugin integration</li>
<li>Cloudflare CDN — API token-based cache purge with zone support</li>
<li>Custom CDN — Any CDN with HTTP purge API (KeyCDN, StackPath, BunnyCDN, Fastly, etc.)</li>
</ul>
