Você precisa desativar o MultiViews:
Options -MultiViews
The effect of MultiViews is as follows: if the server receives a request for
/some/dir/foo
, if/some/dir
has MultiViews enabled, and/some/dir/foo
does not exist, then the server reads the directory looking for files namedfoo.*
, and effectively fakes up a type map which names all those files, assigning them the same media types and content-encodings it would have if the client had asked for one of them by name. It then chooses the best match to the client's requirements.
