"The most important thing to do is to ensure that the OpenLayers Layer has
the same resolutions and bounding box as your TileCache layer. You can
define the resolutions in OpenLayers via the 'resolutions' option or the
'maxResolution' option on the layer. The maxExtent should be defined to
match the bbox parameter of the TileCache layer."

If you can't get it to work, there are two chunks of information that are
neccesary for debugging:
 * TileCache layer config section
 * OpenLayers Map() config and Layer() config.
   (Any other part of the OpenLayers page is not neccesary)
