sni-reader extracts the Server Name Indication from a raw TLS stream. It reads
the ClientHello message and extracts the value of the SNI extension if the
extension is present.
var net = require('net')
var sni = require('sni-reader')
const serverNameMap =
{ 'example.com': 8001
, 'example.net': 8002
}
net.createServer(function(socket) {
sni(socket, function(err, serverName) {
const port = serverNameMap[serverName]
socket.pipe(net.connect(port)).pipe(socket)
})
}).listen(80)npm install -S sni-readerMIT
