Domain routing possibilities in CI?

Well, I guess I should have just tested this out in the first place to get it right the first time.

I set up an installation to work out the bugs, and I got it working. Hopefully it will work for you too! Here's what my .htaccess looks like:

Code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    
    RewriteCond %{REQUEST_URI} !^/index\.php/users/
    RewriteCond %{HTTP_HOST} ^((?!www\.)[^\.]+)\.example\.com
    RewriteRule ^(.*)$ users/%1/$1
    
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.

    ErrorDocument 404 /index.php
</IfModule>
