301 Redirect not working - need help with htaccess file please!

I have created an htaccess file to redirect:

http://www.mydomain.info/index.shtml
and
http://mydomain.info/

to just
www.mydomain.info

But it is not working. The second domain (without the 'www' is working, but the first part (with the index.shtml) gives me this error:

"The page isn't redirecting properly-
Firefox has detected that the server is redirecting the request for this address in a way that will never complete."

. I had to take the htaccess file down, because of the error, but I hope you can help me by seeing my htaccess file:

..............................................................
redirect 301 /index.shtml http://www.mydomain.info

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mydomain.info [NC]
RewriteRule ^(.*)$ http://www.mydomain.info/$1 [L,R=301]
.............................................................


Can you tell me the proper syntax for this line, as obviously I am doing something wrong?

redirect 301 /index.shtml http://www.mydomain.info

Thank you!
