Sorry, please post also Your tilecache configuration?

But,  if You want to have transparent images You should have to change
"IMAGEMODE RGB" to "IMAGEMODE RGBA",  add TRANSPARENT TRUE on MAP
level
and also FORMATOPTION "INTERLACE=OFF" can be set for sure on
OUTPUTFORMAT as well.

In tilecache.cfg You should have  "url=http://your_url&transparent=true"
