What is Varnish, and how does it integrate with Symfony?
Answer: Varnish is a high-performance HTTP accelerator designed to cache web content and improve website response times by reducing server load. It acts as a reverse proxy in front of a web server.
When integrated with Symfony, Varnish can cache the output of Symfony applications, serving cached responses for common requests and reducing response times for dynamic content. Symfony can be configured to include cache directives in HTTP headers, which Varnish uses to determine what to cache and when to invalidate cached items. Additionally, Symfony’s routing and cache management components can be utilized to enhance Varnish’s caching strategy effectively.
