php - .htaccess mapping subdomain to a directory having codeignitor framework -

i know there millons of solution available redirect subdomain directory. still facing problem.

i want map subdomain in following manner

1. demo1.example.com demo1 dir
2. demo2.example.com demo2 dir

i using following code

<ifmodule mod_rewrite.c>     rewriteengine on     rewritebase /     rewritecond %{http_host} ^demo1\.example\.com$     #rewritecond %{request_uri} !^/demo1/     rewriterule (.*) /demo1/$1 [l]      rewritecond %{http_host} ^demo2\.example\.com$     rewritecond %{request_uri} !^/demo2/     rewriterule (.*) /demo2/$1 [l] </ifmodule>  

this working fine but getting dir name in url demo1.example.com/demo1/ have used following rewrite rule

rewriterule ^demo1/(.*)$ /$1 [l,nc,r] 

but unable remove demo1 url have codeigniter framework in demo1 dir having following htaccess

<ifmodule mod_rewrite.c>   rewriteengine on   rewritecond %{request_filename} !-f   rewritecond %{request_filename} !-d    rewriterule ^(.*)$ index.php?/$1 [l,qsa]   </ifmodule>  

if have complete installation of framework in each subdirectory , you're not doing kind of dynamic mapping, rewriting urls isn't best solution.

just create virtual host each installation , set server name accordingly.

<virtualhost *:80>   documentroot /var/www/example.com/demo1   servername demo1.example.com </virtualhost>  <virtualhost *:80>   documentroot /var/www/example.com/demo2   servername demo2.example.com </virtualhost> 

depending on kind of hosting you're using, can create virtual hosts in hosting management backend, or check apache 2.2 docs more information.
