How to redirect all urls to a www. subdomain

Question

I've got this rewrite in my .htaccess:

RewriteCond %{HTTP_HOST}%{REQUEST_URI} ^domain.com/$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [r=301,nc]

Which works fine for domain.com but doesn't redirect the URL with something after the /

(domain.com/something.php should redirect to www.domain.com/something.php)

How can this be done?

Thanks in advance!!

Answer 1

check it out

RewriteCond %{HTTP_HOST} !^www\.domain\.com 
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=permanent,L]

我的猜测是，因为您编写了^domain.com/$ -美元符号的末尾表示字符串的结尾，所以后面没有任何内容-这就是为什么它可以与domain.com一起使用，但是不能与其他功能一起使用吗？
