If you’re looking for a powerful, reliable and efficient web server, look no further than Kestrel. Kestrel is a cross-platform web server for ASP.NET Core, and is the server used by default in Visual Studio. In this article, we’ll take a look at what Kestrel is, how to configure it, and how it can be used to replace IIS as your web server.
What is Kestrel?
Kestrel is a cross-platform web server for ASP.NET Core. It can be used on Windows, Linux and macOS. Kestrel is the default web server used by Visual Studio for ASP.NET Core projects.
Kestrel is a high-performance web server. It is open-source and was built from the ground up to be fast and lightweight. Kestrel is used in production by some of the largest websites in the world, including Stack Overflow, Microsoft Docs, and Microsoft Azure.
How to configure Kestrel
Kestrel can be configured using command-line arguments, environment variables, or configuration files. The recommended way to configure Kestrel is using a configuration file.
Kestrel can be configured to use HTTPS. To do this, you will need to generate a self-signed certificate or obtain a certificate from a certificate authority.
Customize your server, your way
Kestrel is highly customizable. You can configure it to use different ports, different protocols, and different URLs. You can also configure Kestrel to use different middleware. Middleware is software that is used to modify the behavior of a web server.
How Microsoft replaced IIS with Kestrel
Microsoft has replaced IIS with Kestrel as the default web server for ASP.NET Core. This change was made because Kestrel is a cross-platform web server, whereas IIS is a Windows-only web server.
Microsoft recommends using IIS as a reverse proxy server for Kestrel. This means that IIS will handle all incoming requests, and then forward those requests to Kestrel. IIS can also be used to load-balance requests between multiple instances of Kestrel.
Conclusion
Kestrel is a high-performance, cross-platform web server for ASP.NET Core. It is the default web server used by Visual Studio, and can be used to replace IIS as your web server. Kestrel is highly customizable, and can be configured to use different ports, different protocols, and different URLs.
