Answer 1

Using nginx, this a solution without the need to change anything in the socket.io server app:

In the nginx conf:

location /mysubdir {
   rewrite ^/mysubdir/(.*) /socket.io/$1 break;
   proxy_set_header Upgrade $http_upgrade;
   proxy_set_header Connection "upgrade";
   proxy_http_version 1.1;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header Host $host;
   proxy_pass http://127.0.1.1:3000;
}

In the server:

var io = require('socket.io')(3000)

In the client:

var socket = io.connect('https://example.com/', {
    path: "/mysubdir"
})
