You need to make sure things like "./../../test" is not allowed. But
you also need to filter backslash, and possibly other characters,
specially escape sequences (search Google for "Double Decode File
System Traversal").

I think it's more secure to whitelist known good characters (a-z, A-Z,
_, 0-9) than to blacklist known bad ones, as you can't be completely
sure which are the bad ones.

Regards,
Thomas
