Easy htaccess condition

[withoutnick]

Hello, I am total begginer here. I would be grateful if you could help me.

I have this rewrite condition + rewrite.

RewriteCond %{REQUEST_URI} ^([^/]*).html$ [NC]
RewriteRule ^(.*).html$ index.php?page=$1 [L,QSA]

When i test it, i get page not found. Online regex tester, matches the result without no error.

The htaccess file is one level deeper than home dir: the address would be http://www.mydomain.com/regex_directory/

Thank you.

I did a modification to regex

RewriteCond %{REQUEST_URI} .([^/])*.html$ [NC]
RewriteRule ^(.*).html$		index.php?page=$1 [L,QSA]

Now it matches the request: mydomain.com/directory/index.html

But as well it matches and mydomain.com/directory/inde/x.html

$_GET variable page than is shown as inde/x?

What is wrong with my regex?
