Description: The Nginx Proxy Cache is a feature that allows Nginx to cache responses from proxy servers, thereby improving the efficiency and speed of content delivery to users. This feature is based on Nginx’s ability to intercept client requests and, instead of sending each request to the origin server, it can serve previously stored responses. This not only reduces the load on the origin server but also decreases latency, as responses can be delivered more quickly from the cache. Nginx uses a configurable caching system that allows administrators to define policies on what content to store, for how long, and how to invalidate the cache when necessary. Additionally, the Nginx Proxy Cache is highly scalable, making it a popular choice for high-traffic websites and web applications. Its integration with other Nginx features, such as compression and load balancing, makes it a powerful tool for optimizing web application performance. In summary, the Nginx Proxy Cache is essential for improving speed and efficiency in content delivery, resulting in a better experience for the end user.
