TileCache isn't exactly a WMS proxy. It implements a WMS-C client and
server. WMS-C clients can make requests from WMS servers
transparently, but WMS clients must take care to align requests to the
layer's tile grid when requesting from a WMS-C server (like
TileCache). Are you requesting gridded tiles from MapServer?

It would actually be a pretty useful feature to have TileCache seam
together tiles as a configuration option and deliver them via regular
WMS, but I'm pretty sure someone would need to submit a patch.
