Hello!

I've entered a redirect code into the .htaccess according to one's IP:

RewriteCond %{REMOTE_ADDR} ^80\.178\.57\.190$
RewriteRule .* /index.HTML

It worked, but today I started to get this error:

Bad Request
Your browser sent a request that this server could not understand.

Additionally, a 400 Bad Request error was encountered while trying to use an ErrorDocument to handle the request.

Would anyone know what could be the cause?

Thanks!

maybe the use of uppercase

*nix webservers are case sensitive
