websockets and erlang

After a little experimentation I've got websockets and erlang playing together.

This means we can now do pure asynchronous I/O with a browser - no
long-poll, no comet, no server-polling, no ajax and a major source of
server inefficiency (HTTP header parsing) is totally eliminated.


    On your web page you write

        <div id="tag1"></div>

    In Erlang you say

        Browser ! {send,  "tag1 ! XYZ"}

     Then the inside of the div is set to the string XYZ

     This presupposes that you have Google chrome, a local web server and a
web page with some suitable javascript to decode the incoming messages.
