apache redirect from non www to www

Question

I have a website that doesn\'t seem to redirect from non-www to www.

My Apache configuration is as follows:

RewriteEngine On
### re-direct t         


        

Answer 1

This is similar to many of the other suggestions with a couple enhancements:

• No need to hardcode the domain (works with vhosts that accept multiple domains or between environments)
• Preserves the scheme (http/https) and ignores the effects of previous %{REQUEST_URI} rules.

• The path portion not affected by previous RewriteRules like %{REQUEST_URI} is.

  RewriteCond %{HTTP_HOST} !^www\. [NC]
  RewriteRule ^(.*)$ %{REQUEST_SCHEME}://www.%{HTTP_HOST}/$1 [R=301,L]
