A tile size of 512 X 512 is a last option that I want to consider. I was hoping the caching mechanism would still work with a 256 X 256 tile size, but without the issue of the zoom going past the maxExtent defined. Just wondering if this is a known issue (maybe it's a dumb question :-) ... i dont understand the workings of OpenLayers that well right now. )

This is something which i dont want to happen. What do you want to have happen? I'm assuming you want 512px by 512px of tiles -- 4 of them, in other words? -- Chris > When looking through the code for geowebcache and OpenLayers i noticed that > geowebcache maintains a resolution array corresponding with a tile width of > 256.
