Description

Varnish is an open source web application accelerator and content delivery network that helps to improve the performance, scalability and reliability of web applications and websites. It works by caching web pages and other content in memory and then delivering them to the user faster than they would have been served directly from the web server. Varnish also helps to protect websites from malicious attacks, such as DDoS (Distributed Denial of Service). It can also be used to speed up page loading times by caching content and serving it from a local server. Varnish also provides security features like URL filtering and IP address blocking, which can be used to prevent malicious traffic from reaching a website. Additionally, Varnish can be used to implement other security measures such as rate limiting and content filtering.
