IO

IO(url:String, opts:Object):Socket

Exposed as the io global in window if using the standalone build (eg: /socket.io/socket.io.js or the CDN), or the result of calling require('socket.io-client').

When called, it creates a new Manager for the given URL, and attempts to reuse an existing Manager for subsequent calls, unless the multiplex option is passed with false. Passing this option is the equivalent of passing 'force new connection': true.

The rest of the options are passed to the Manager constructor (see below for details).

A Socket instance is returned for the namespace specified by the pathname in the URL, defaulting to /. For example, if the url is http://localhost/users, a transport connection will be established to http://localhost and a Socket.IO connection will be established to /users.
