Not sure if that was the answer you were after Francesco, the way I read your question was a bit different, and to do what I think you're trying to do you can use layer event listeners.. which will basically do what you want.

i.e loadstart and loadend events.
<code>  layer.events.register("loadstart", layer, function() {                this.logEvent("Load Start");
            });orlayer.events.register("loadend", layer, function() {                this.logEvent("Load End. Grid:" + this.grid.length + "x" + this.grid[0].length);
            });</code>
Taken from 
http://dev.openlayers.org/releases/OpenLayers-2.11/examples/layerLoadMonitoring.html

which doesn't actually work but look at the source..

Remember: OpenLayers is a JAVASCRIPT framework, so, javascript knowledge is gold!
