Kestrel
Microsoft
Kestrel serves as a versatile web server for ASP.NET Core applications, being the default server integrated into project templates. It provides support for various protocols including HTTPS and HTTP/2, though the latter is not available on macOS, and facilitates WebSockets through an opaque upgrade feature, along with Unix socket support for enhanced performance when operating behind Nginx. This web server is compatible with all platforms and versions that .NET Core accommodates. Developers must be aware that some browsers necessitate explicit permission to accept the local development certificate, and project templates are pre-configured to utilize HTTPS by default while also integrating HTTPS redirection and HSTS features. Kestrel offers specific configuration options that are particularly beneficial for deployments exposed to the internet, with distinct connection limits for those upgraded from HTTP or HTTPS to other protocols, such as during WebSocket requests. Notably, the server has a default limit for the maximum request body size set at approximately 28.6 MB, or 30,000,000 bytes, ensuring efficient handling of requests. Additionally, the flexibility of Kestrel allows developers to fine-tune these parameters according to their application's specific requirements. -
