nginx-multiplexer

TCP and/or TLS-alpn multiplexer just by nginx conf

You don't need to use any other tools like sslh or sshttp.

1. TCP multiplexer.

Using nginx script to run multiple tcp protocols at the same port: http, ssl, and ssh.

```
# In file: /etc/nginx/nginx.conf

#load nginx script module
load_module modules/ngx_stream_js_module.so;
load_module modules/ngx_http_js_module.so;

http {
  #The real  http server listen at 80
  listen 80;
  ....
  
  #The real  https server listens at 8443
  listen 8443 ssl;
  ....
}


stream { 
  
  #Inport the js file first
  js_import /etc/nginx/stream.d/mul.js;
  
  
  server {
      # Them multiplexer listens at the public 443 port
      listen 443;
      resolver 1.1.1.1 8.8.8.8  valid=300s;

      set $upstream "127.0.0.1:8443"; #default to loacalhost 8443

      js_preread mul.preread;

      proxy_pass $upstream;
  }

}


```
