Automatically chunk HTTP/1.1 Connection: close responses

[halter73]

Chunked responses seem more reliable than relying on the TCP connection to close in order to end the response. Kestrel is changing it's behavior in 1.1 to automatically chunk HTTP/1.1 responses, even if they have the Connection: close header is set.

More context can be found here: aspnet/KestrelHttpServer#962 (comment)

Also FWIW, node.js follows the behavior I'm recommending. The following app will chunk given HTTP/1.1 request, but not for HTTP/1.0 requests of course.

var http = require('http');

var server = http.createServer(function (request, response) {
  response.writeHead(200, {"Content-Type": "text/plain", "Connection": "close"});
  response.end("Hello World!");
});

server.listen(8000);
console.log("Server running at http://127.0.0.1:8000/");
