htaccess www redirect for seo friendly url

问题

Here's what I want:

URL: http://www.domain.com/location/netherlands/amsterdam/amsterdam-airport

Now, what I want is if anyone open this url without www, he should get redirected to www.

Remember these are seo friendly url. I am already using MOD_REWRITE for the above url:

RewriteRule ^location/([^/]+)/?([^/]*)/?([^/]*)/?$ /location.php?country=$1&city=$2&location=$3 [L,QSA,NC]

Now if I do www redirect using any htaccess tricks. This is what I get:

http://www.domain.com/location.php?country=netherlands&city=amsterdam&location=amsterdam-airport

If you have any questions, let me know. Thanks!

Make sure to have www rule before this existing rule:

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

RewriteRule ^location/([^/]+)/?([^/]*)/?([^/]*)/?$ /location.php?country=$1&city=$2&location=$3 [L,QSA,NC]

Also make sure to test in a different browser or clear your browser cache before testing.
