WPS-Cache enhances your WordPress site’s speed by implementing multiple layers of caching: 
– HTML Cache: Delivers pre-rendered static pages. 
– Redis Cache: Accelerates database query performance. 
– Varnish Cache: Handles HTTP-level caching for improved scalability.
<h3>External Services</h3>
This plugin connects to external caching services to optimize performance:
<ul>
<li>Varnish Cache: 
The plugin sends HTTP requests (such as purge requests and connection checks) to a specified Varnish caching server. No personal or sensitive data is transmitted. For additional details, please review the <a href="https://varnish-cache.org/" rel="nofollow ugc">Varnish Cache documentation</a>, its <a href="https://varnish-cache.org/TOS" rel="nofollow ugc">Terms of Service</a>, and <a href="https://varnish-cache.org/privacy" rel="nofollow ugc">Privacy Policy</a>.</li>
</ul>

WPS-Cache

Boost your WordPress speed with multi-layer caching: HTML, Redis, and Varnish for fast performance.

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.
