htaccess www to non-www redirect (and config.php)

Question

I need to set up a redirect from the www version of my site to the non-www version for SEO. I found a solution that would work here if it weren't for the fact that it breaks the index.php redirect that comes with craft.

Can anyone tell me how to implement a generic redirect from http://www.site.co.uk to http://site.co.uk and still keep the index.php craft redirect working?

Additionally, does this affect the config.php file, or does that get loaded AFTER the redirect?

Thanks!

Providing you have the necessary permissions to do this, the following in your .htaccess should do the job:

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

In place, the full file will probably look something like this:

<IfModule mod_rewrite.c>
RewriteEngine On

# Redirect to non-www domain
RewriteCond %{HTTP_HOST} !^domain\.co\.uk$ [NC]
RewriteRule ^(.*)$ http://domain.co.uk/$1 [R=301,L]

# Send would-be 404 requests to Craft
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
RewriteRule (.+) index.php?p=$1 [QSA,L]
</IfModule>

The following seems to work for me as a generic option:

<IfModule mod_rewrite.c>
RewriteEngine On

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

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

# Send would-be 404 requests to Craft
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC]
RewriteRule (.+) index.php?p=$1 [QSA,L]
</IfModule>
