If you're trying to do case-insensitive files with Drupal, forget about it! Unless you redo the whole mod rewrite stuff. basically when you request a file, the mod_rewrite shoots it through Drupal first as a query param. Even if you turn on CheckSpelling in apache, it won't work. I don't have a solution, except not to use mod rewrite or clean URLs. OR... not use CheckSpelling which is what most security experts recommend anyway. Make your choice!
