细节请看官方文档。我个人接触到的就是，使用xmpp可以开发IM应用。
stream {
# webserver
upstream httpserver {
server localhost:8443;
}
# xmppserver
upstream xmppserver {
server localhost:5666;
}
map $ssl_preread_alpn_protocols $upstream {
default httpserver;
"xmpp-client" xmppserver;
}
server {
listen 5666;
ssl_preread on;
proxy_pass $upstream
}
}
