i was 100% sure my .htaccess/mod_rewrite was working, but now it seems to have stopped working.

this is what i want it to do:

if there is NO HTTP_REFERER, then redirect the customer to www.yahoo.com. but it's not working ( i get cannot find server or permission denied errors )

here is my .htaccess file. can anyone help?


RewriteEngine on

RewriteCond %{HTTP_REFERER} ^$
RewriteRule ^(.*)$ http://www.yahoo.com/ [L,F]
