使用htaccess重定向

I want to redirect '/' or '/index' to '/user' action in zend2. I googled it but still I haven't found a solution.

The htaccess code is:

SetEnv "APP_ENV" "developement"

Options +FollowSymLinks
RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*)/$ /$1 [R,L]
RewriteRule ^.*$ index.php [NC,L]
