Redirect all non www visitors to the www [closed]

Question

I keep getting variations of the following answer, and it doesn't work

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

The reason this solution is no good is that if I go to

alwaysromaing.com/site

I'll never get be redirected to the WWW.alwaysroaming.com/site

Can anyone provide the correct rewrite required here?

Answer 1

I'd suggest this:

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

The key part is the '/' after the '^' in the second line. The NC in means it'll work if someone types in mixed/upper case.

Answer 2

This is such a common question that it's part of the documentation for mod_rewrite - which you did read, right?

Assuming you're running on port 80:

RewriteCond %{HTTP_HOST}   !^fully\.qualified\.domain\.name [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteRule ^/(.*)         http://fully.qualified.domain.name/$1 [L,R]

the documentation has another example in case you're not on port 80, and covers other common scenarios
