Rewriting problem with .htaccess (removing /index.php from CodeIgniter URLs)

Question

I have a small issue with some .htaccess rules on our website - http://www.presencemultimedia.co.uk

We've recently re-built the website using CodeIgniter. To use nice URLs I've added some lines to our .htaccess file as below :

RewriteEngine on

# CodeIgniter rules (forwards requests to index.php)
RewriteCond $1 !^(index\.php|images|robots\.txt|public)
RewriteRule ^(.*)$ /index.php/$1 [L]

# rewrites path to our primary domain (www.presencemultimedia.co.uk)
RewriteCond %{http_host} !www.presencemultimedia.co.uk$
RewriteRule ^(.*)$ http://www.presencemultimedia.co.uk/$1 [r=301,nc]

The second rewrite rule is designed to ensure the domain is always our primary domain (www.presencemultimedia.co.uk).

The issue I have is that if the website is accessed by an aliased domain, e.g. http://www.prmulti.com, the URL is rewritten to the primary domain but adds /index.php/ to the path.

For example - http://www.prmulti.com/about/ should rewrite to http://www.presencemultimedia.co.uk/about/ instead of http://www.presencemultimedia.co.uk/index.php/about

Can anyone see where I'm going wrong?

Cheers, Phil

Answer 1

I would have thought the 301 re-direct should be above your CodeIgniter rules, giving:

RewriteEngine on

# rewrites path to our primary domain (www.presencemultimedia.co.uk)
RewriteCond %{http_host} !www.presencemultimedia.co.uk$
RewriteRule ^(.*)$ http://www.presencemultimedia.co.uk/$1 [r=301,nc]

# CodeIgniter rules (forwards requests to index.php)
RewriteCond $1 !^(index\.php|images|robots\.txt|public)
RewriteRule ^(.*)$ /index.php/$1 [L]

I recently developed a multi-site framework for a website, and that's the order of re-writing I'm using: domain first, then direct the result through my index.php. The theory should be the same for an off-the-shelf framework like CodeIgniter.

I had luck with this configuration:

RewriteEngine on

# rewrites path to our primary domain (www.presencemultimedia.co.uk)
RewriteCond %{http_host} !www.presencemultimedia.co.uk$
RewriteRule ^(.*)$ http://www.presencemultimedia.co.uk/$1 [r=301,nc,l]

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

If the domain rule matches, redirect (but making it the last rule). Then on the correct domain, if the request isn't an existing file or directory, pass to Code Igniter.
