People,

I am trying to design a messenging system that is being triggered by
server events. As I want to prevent polling, I resend a new
XMLHttpRequest every time when the one before has just done its job.

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            // do something with the incoming response
            ...
            // fire a new XMLHttpRequest
            ...
            xmlhttp.send(null);
        }
    }

It seems that Chrome shows its progress icon when a XMLHttpRequest is
in progress (as opposed to IE). Can I supress this somehow? I want to
give the user a 'static' experience. My webapp shouldn't be showing
such a progress icon.

Thanks for your help,
Carl
