Varnish Cache
A high-performance web accelerator that stores cached pages in memory, allowing faster delivery for high-traffic websites hosted online.
Varnish Cache is a powerful web application accelerator that sits between your visitors and your web server, storing frequently accessed content in memory for lightning-fast delivery. When a user requests a page, Varnish serves the cached version from RAM instead of making the server generate it from scratch, dramatically reducing load times and server resource consumption. This is particularly valuable for high-traffic websites, content-heavy platforms, and sites experiencing sudden traffic spikes. Varnish can handle thousands of requests per second, making it ideal for news sites, e-commerce platforms, and popular blogs. It works by caching HTTP responses and intelligently deciding what to cache, when to refresh cached content, and when to fetch fresh data from the origin server. Many hosting providers offer Varnish as an optional or included feature for VPS and dedicated hosting plans, providing significant performance improvements without requiring changes to your website code or structure.
