Simple .htaccess help

Hi,

I have a simple .htaccess question.

I want to 301 redirect this way

mysite.com/profile.php?user=username to mysite.com/username/

 

use this

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*)/$ /profile.php?user=$1

Code (markup):

 

When I do that nothing happens. When I go to my old page mysite.com/profile.php?user=username i want the page to be automatically redirected to the new page mysite.com/username/

 

.htaccess wont redirect u have to modify ur php code to do that

 

What about those 301 redirects? Won't they work too?

 

They will just redirect the same as this but to change the urls in the script u have to modify the code
