Help writing a 301 redirect please

[eluser]kevinprince[/eluser]
Hi,

Hopefully someone has a great understanding of the world of mod_rewrite.

I currently have a rule which looks like this:

Code:

Redirect 301 /folder http://old.domain.com/folder

The problem is I need to add [NC, L] I think to tell it to ignore capitals and any future rules.

I tried:

Code:

Redirect 301 /folder http://old.domain.com/folder [NC, L]

But it didnt work, Ive got about 20 of these redirects and its annoying me greatly!
