I would like to use .htaccess to point any calls to http://example.com/ to http://www.example.com including whether a page is specified. That is, http://example.com/contact.html would redirect to to http://www.example.com/contact.html.
Can someone help with the syntax as I've tried different examples and it won't work.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
Trivia: If you are using an example or placeholder domain, please use example.com. This domain has been reserved specifically for this purpose in RFC2606.
You can use this, it'll work on any domain without editing:
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
I've written a small Apache plugin that might be helpful here, it's called "RedirToServName" and can be found in my software dump at http://www.hogyros.de/download/ . Documentation is a bit lacking; in essence all it does is generate redirects if the host name is not the canonical hostname from the ServerName directive.
Granted, using a dedicated plugin for that seems like overkill, but I find that it leaves less room for misconfiguration, as the only configuration variable is a boolean to turn it on.
