HttpRequest.redraw method does the same thing, so the additional call
to mergeNewParams looks unnecessary
see: http://trac.osgeo.org/openlayers/browser/trunk/openlayers/lib/OpenLayers/Layer/HTTPRequest.js
redraw: function(force) {
if (force) {
return this.mergeNewParams({"_olSalt": Math.random()});
} else {
return OpenLayers.Layer.prototype.redraw.apply(this, []);
}
},
