WordPress MU

Hi, I was wondering if someone could help me figure out how to change a 302 redirect to a 301. Currently http://www.emoscene.com does a 302 redirect to emoscene.com, I looked at the .htaccess file, but I can't figure it out and I don't want to mess up anything that WPMU needs. I tried changing it to [R=permanent,L] but that gave me a 500 error.

RewriteEngine On
RewriteBase /

# Rewrite http://www.domain.com to domain.com
RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^(.*)

http://%1/$1 [R,L]

#uploaded files
RewriteRule ^(.*)?/?files/(.*)

wp-content/blogs.php?file=$2 [L]

RewriteCond %{REQUEST_FILENAME} -f

[OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule

^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Well, it redirected invisibly for me, but this is the line that does it:

RewriteCond %{HTTP_HOST} ^www\.(.*)

It's recommended you leave it there though.

Ok, I figured it out.. Its in the line

RewriteRule ^(.*) http://%1/$1 [R,L]

All I had to do was change [R=301,L] The example I saw said to do [R=permanent,L], which didnt work for me.

It was redirecting invisibly, but it was a 302 redirect, which isn't search engine friendly.
Thanks for the input though, I always appreciate your help :)
