[Tilecache] Tilecache request problem

[cmose]

Does your open layers map declaration also have the same resolutions array
defined? If so, is that you show as an example request coming from an
overview map control? The overview map needs to be passed an options object
with mapOptions:{resolution:[]} where resolutions:[] is the same as what is
defined in your main  map. Other then a disconnect between your OL map
declaration/configuration and TileCache I'm not certain what else could
cause that (although I'm pretty sure there are other less obvious and subtle
issues that can contribute to such an error message).
cheers
