About Kestrel

Kestrel is a cross-platform web server for ASP.NET Core. Kestrel is the web server that's included and enabled by default in ASP.NET Core project templates. Kestrel supports HTTPS, HTTP/2 (except on macOS), Opaque upgrade used to enable WebSockets, Unix sockets for high performance behind Nginx. Kestrel is supported on all platforms and versions that .NET Core supports. Some browsers require granting explicit permission to trust the local development certificate. Project templates configure apps to run on HTTPS by default and include HTTPS redirection and HSTS support. The Kestrel web server has constraint configuration options that are especially useful in Internet-facing deployments. There's a separate limit for connections that have been upgraded from HTTP or HTTPS to another protocol (for example, on a WebSockets request). The default maximum request body size is 30,000,000 bytes, which is approximately 28.6 MB.

Socket.IO
Socket.IO
In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect. Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables low-latency, bidirectional and event-based communication between a client and a server. It is built on top of the WebSocket protocol and provides additional guarantees like a fallback to HTTP long-polling or automatic reconnection. WebSocket is a communication protocol that provides a full-duplex and low-latency channel between the server and the browser. There are several Socket.IO server implementations available. And client implementations in most major languages.
