URL Rewrite Question

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1

Hi this works ok for:

http://domain/user

but not for:

http://domain/user/

What should I add to make the trailing slash at the end take?

Thanks.


EDIT:

Answer:

RewriteEngine on
RewriteRule ^([^/\.]+)/?$ user.php?username=$1

RewriteEngine on
RewriteRule ^user/([^/\.]+)/?$ user.php?username=$1 [NC]
