virtual subdomain with htaccess

[eluser]harmstra[/eluser]
Maybe that's how things are in theory.
This is how tings are on my server in real life

/test is a physical directory

Code:

RewriteCond %{HTTP_HOST} ^subdomain[NC]
RewriteRule ^(.*)$ http://www.onderdelenzoeker.com/test/$1 [QSA,L] #no change in address bar

/test is a NOT a physical dir, but a controller

Code:

RewriteCond %{HTTP_HOST} ^subdomain[NC]
RewriteCond %{REQUEST_URI} !^/index.php/test[NC] # to prevent loop
RewriteRule ^(.*)$ http://www.doamin.com/index.php/test/$1 [QSA,L] #address bar changes

So what's the difference? I think the problem is this

The code used for CI

Code:

RewriteCond $1 !^(index\.php|images|robots\.txt|src|ext)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [QSA]

In the first case, the dir exists, in de second it doesn't
So in the second case, the above RewriteRule will be executed, in the first case it won't.
