Kestrel

Kestrel is a lightweight, high-performance web server used in .NET applications to handle incoming internet requests. It efficiently manages multiple connections, serving web pages or APIs quickly and securely. Kestrel is often integrated into larger web systems, sometimes behind a reverse proxy like IIS or Nginx, which helps with additional features like load balancing and security. By providing fast, scalable, and reliable request processing, Kestrel ensures web applications remain responsive and capable of handling many users simultaneously.
