Connection error unable to reproduce in local env

[Bratish Goswami]

While the localhost working perfectly, the similar thing showing
problem from remote production server. The js error is something like:

The connection to ws://remote.server:8088/socket.io/1/websocket/1221615574727743779
was interrupted while the page was loading.

The problem is very much Firefox specific I am assuming. Firefox
version is 8.0.1.

It's throwing error around this line of the client side socket.io.js
file:

e=c.MozWebSocket||c.WebSocket),this.websocket=new e(this.prepareUrl()
+a),this.websocket.onopen=function(){

Any idea why this is happening?

Thanks

The user closed the page, or pressed the esc button which closes all
connection even websocket connections.
