[OpenLayers-Dev] OpenLayers map.AfterDraw event

[geojoe]

I would like to save the map extent to cookies so I can use it on a page
refresh.

Is there an AfterDraw event and if not how do I create it so it will fire
the function below?

function saveMapExtentCookies() {
	var bounds = map.getExtent();
	var date = new Date();
	var days = 1;

	alert(bounds.Left);

        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
	document.cookie = "'mapExtentLeft'="  +bounds.Left    +expires;
	document.cookie = "'mapExtentBottom'="+bounds.Bottom +expires;
	document.cookie = "'mapExtentRight'=" +bounds.Right  +expires;
	document.cookie = "'mapExtentTop'="   +bounds.Top    +expires;
}


Thanks
