Code:
RewriteEngine on
Rewriterule index.php/feed/ http://www.domain.com/ [R=301,L]
not sure exactly where you want it to head, but,
http://www.domain.com/ will redirect it to the root of the domain with the www. preceding.
you might consider replacing:
Code:
RewriteRule (gif|jpg|png|swf|mpg|avi|GIF|JPG|PNG|SWF|MPG|AVI)$ http://www.domainname.com [R,L]
with
Code:
RewriteRule (gif|jpg|png|swf|mpg|avi|GIF|JPG|PNG|SWF|MPG|AVI)$ http://www.domainname.com/ [R=301,L]
Since your other rewrite will do a 302 and you might be unintentionally scraping your results. Without the trailing / on the url, you would also force the surfer (or spider) to have to do a 301 redirect to properly grab the file at the root.
