Yeah, sorry for not making this more public before. This has been in
production use for a good while now. I'll bundle it up as a patch.

Best regards,

Iván, this looks pretty cool. Is there any reason not to rename the layer
to OpenLayers.Layer.GeoWebCache? I'd recommend doing so, and then filing a
ticket in Trac for inclusion in OpenLayers.

Hi all,
I'm working in a project that involves running GeoServer+GeoWebCache to
generate a whole bunch of tiles, then copying all the unmodified cached
tiles
to a frontend., then put openlayers on top.
The trick is that GWC's way of naming cached tiles looks like this:
EPSG_$projection_$namespace_$layer_08/05_04/0161_0146.png
Here, 08 is z, 0161 is x, and 0146 is y. But the zero-padding and that
mid-level directory prevents us from using XYZ or TMS.
Worry no more! The brand-new GWC layer allows to load a mirrored copy of
GWC's
tile cache with no hassle, even accounting for GWC's bugs! Looky here:
http://ivan.sanchezortega.es/GWC.js
Usage is pretty straightforward:
var gwc = new OpenLayers.Layer.GWC({});
gwc.url = "path_to_cache_dir/EPSG_12345_namespace_layer_";
gwc.type = 'png';
gwc.name = "foobar"
map.addLayer(gwc);
Best,
