Home How to do an internal redirect with CodeIgniter for robots.txt?
 I have a server running Apache 2.2.24 and CodeIgniter 2.1.0 . I want to handle requests for /robots.txt dynamically, using CodeIgniter, but the only solution I have found so far is to use .htaccess to issue a temporary redirect that tells clients to fetch /robots_txt instead (note the underscore). RewriteRule ^robots\.txt$/robots_txt [NC,L,R=307]  Later in the .htaccess there are these rules for CodeIgniter: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/\$1  Within CodeIgniter I can route requests for robots_txt to a controller. My question is, how can I change this to an internal redirect? That is, when I get a request for robots.txt, instead of issuing a redirect response to the client, how can I rewrite the url to handle it internally as robots_txt? Anything I have tried leads to a 404.
