HTML 5 web sockets and XMPP Server dialog

Does using web sockets actually mean browsers will be able communicate开发者_如何学编程 with xmpp servers (any other IM servers) directly ?

Thx.

No. Allowing TCP-level access to arbitrary servers would cause all kinds of security problems. Imagine a website which caused every user to connect to an SMTP server and start sending spam emails… suddenly you have a massively distributed spam attack, especially if combined with an XSS attack on a major site. Web Sockets has a small amount of framing around it designed to make such attacks impossible, without adding too much overhead over TCP.

One day. It's likely that we'll define an XMPP sub-protocol for websockets that can replace BOSH(XEP-0124/0206) when both the client and server support it. In the meantime, BOSH is widely implemented.

you can think of HTTP polling .... and transfer xmpp data along 8080 port..
