I got problems with the following two lines:

```
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^(.+[^/])$ /$1.html [L]

```

Goal: Redirecting "domain.tld/test/" (only if test.html exists) so that it outputs the contents of "domain.tld/test.html".

* How to make this case-insensitive: "domain.tld/Test" -> domain.tld/test.html \*\*
* How to make it accept a trailing slash: "domain.tld/test/" should work, too

Thanks!

\*\* I couldn't get RewriteMap lowercase int:tolower to work, any help appreciated.
