[OpenLayers-Users] Create a layer with multiple GPX source

[snowsar]

Hello everyone,

Currently, I have an application loading a GPX file into a layer :

                 MyLayer = new OpenLayers.Layer.Vector("GPX", {
                     protocol: new OpenLayers.Protocol.HTTP({
                         url: "my_remote_gpx_file.gpx",
                         format: new OpenLayers.Format.GPX()
                     }),
                     strategies: [new OpenLayers.Strategy.Fixed()],
                     styleMap : BuildStyleMap("#9A03FE"),
                     projection : localProjection
                 });
                 map.addLayer(MyLayer );

All is OK with this.

I want now to be able to build a unique layer with several GPX files.
What is the best way to do this ?
Should I inheritate  OpenLayers.Protocol.HTTP to permits string array in 
"url" and use internally OpenLayers.Protocol.HTTP for each one ?

Thank you for your advices.

Regards
