Question

Trying to combine two htaccess RewriteRules at the same time:

1) transform all non-www URLs to www
2) send all requests to index.php

Number 2 works with the following settings in production:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [QSA]

but when combined with

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

the URLs behave as supposed to when using a www url, but funnily when used with a non-www url.

E.g.
http://mydomain.com/customername/admin/signin becomes
http://www.mydomain.com/index.php/admin/signin?/customername/admin/signin

although the URL should just stay the same without a refresh and the parameters “/customername/admin/signin” should be passed to index.php…

Any tips on how I can achieve this? I want the URL after mydomain.com to stay the same (as my solution currently does) but add the www. infront of the URL.

Answer 1

It looks like you just need to add the HTTP_HOST checking before the catch-all rewrite to index.php.

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

This redirects to www before any of the URI have been rewritten to the catch-all, then:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [QSA]

Do the catch-all, which happens after the non-www gets 301 redirected to the www domain.
