Socket.io - 限制最大连接数？

Question

Let's say I want only up to 100 users to join my server. Is there a way to do this internally?

Something like:

io.maxConnections = 100; //If client connections == 100, refuse next client connection

Answer 1

Based on @turivishal's answer, I found:

server.maxConnections = 100;//Max number of connections
