[Tilecache] Why is the bounding box/resolution from the original request not honored?

[chris marx]

Hi,
 Sorry about the bad link everyone, the site is now up

http://warbler2.cit.cornell.edu/pfw-maps/wms-without-cache.html

you can see that the tiles line up just fine (except when you zoom out from
the initial zoom, i believe this is a manifold wms problem, i'm looking into
that) but zooming in is ok. if you're looking at the wms requests, in
firebug, these same requests generate the

An error occurred: Current y value 37.718590 is too far from tile
corner y 37.968750


when i put tilecache in front of the wms.
I appreciate any advice!
