mod_rewrite subdomain and clen url in codeigniter

Question

I suppose my domain is "www.domain.com" and I have a file system

public_html
   |----ds
        |--application
            |--cache
            |--controller
                 ...

        |--css
        |--image
        |--system
        |--index.php
   |----zs
   |----fd

public_html is root directory.

I coding in .htacess with have condition this ::

1) ds Directory is subdomain. when URL is ds.domain.com. It mapping filepath in www.domain.com/ds/index.php/

2) I want to clean URL form www.domain.com/ds/index.php/translate/paintext (example full url) to ds.domain.com/translate/paintext (clean url)

how to coding in .htacess ?

/ ******************************************************************** /

I put the .htacess in /ds folder and try to coding :

#subdomain to subdirectory
RewriteCond %{HTTP_HOST} ^www.domain.com/ds/
RewriteRule ^(.*)$ http://ds.domain.com/$1 [L,R=301]    

#clean URL from codeigniter 
RewriteCond $1 !^(index\.php|lib|css|image)
RewriteRule ^(.*)$ index.php/$1 [L]

What is wrong??

Answer 1

At least one thing that is wrong is your HTTP_HOST . That variable is the hostname , and hostnames contain no URL path info in them. So www.domain.com/ds/ will never exist as a hostname. Change it to:

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

The second issue looks fine. But if you want to redirect a request for /index.php to a new URL that doesn't have the "index.php" part, you need a new rule to do that:

RewriteCond %{THE_REQUEST} \ /+index\.php/
RewriteRule ^index.php/(.*)$ /$1 [L,R=301]
