[OpenLayers-Users] Re: Adding querystring parameter containing current map resolution

[BMcBride]

Steve,

You could register a moveend event for your layer, which would refresh the
layer and pass in your URL parameters. I'm not sure if this would conflict
with your BBOX strategy, but you could use this method to build your own
custom strategy instead.

map.events.register("moveend", this, function () {
        if (MyLayer.getVisibility() === true) {
            refreshMyLayer();
        }
    });

function refreshMyLayer() {
    var resolution = map.getResolution();
    MyLayer.refresh({
        force: true,
        params: {
            res: resolution
        }
    });
}
