Redirecting non-www URL to www using .htaccess

Question

I\'m using Helicon\'s ISAPI Rewrite 3, which basically enables .htaccess in IIS. I need to redirect a non-www URL to the www version, i.e. example.com should redirect to ww

Answer 1

Can't you adjust the RewriteCond to only operate on example.com?

RewriteCond %{HTTP:Host} ^example\.com(.*) [NC]
