301 Redirect from / and /folder/index.php to /folder/

I want to 301 redirect from www.domain.tld/ to www.domain.tld/folder/ which I can get to work this way:

RedirectMatch permanent ^/$ http://www.domain.tld/folder/

Code (markup):

But at the same time I want to 301 redirect from www.domain.tld/folder/index.php to www.domain.tld/folder/

I searched really long, but I can't get it to work. I guess I will have to just use mod_rewrite (and not mod_alias). Anybody experienced out there who could help me? Thanks in advance!

 

try

Redirect 301 / http://domain.tld/


for file

Redirect /file.ext http://domain.tld/
