Redirect sub domain to other IP address without changing sub domain name getting internal server error

Question

I want to redirect from domain_name/directory_name/file_name/ to http://xx.xx.xx.x/project_name/controller/ but in URL I want to show domain_name/directory_name/file_name/. For that I write following code in .htaccess file

  RewriteEngine On
  RewriteCond %{HTTP_HOST} !directory_name/file_name/$ [NC]
  RewriteRule ^(.*)$ http://xx.xx.xx.x/project_name/controller/$1 [P]

When I write

  RewriteEngine On
  RewriteCond %{HTTP_HOST} !directory_name/file_name/$ [NC]
  RewriteRule ^(.*)$ http://xx.xx.xx.x/project_name/controller/$1 [L,R=301]

Then it is redirect from directory_name/file_name/ to http://xx.xx.xx.x/project_name/controller/ but showing http://xx.xx.xx.x/project_name/controller/ in URL.

For that I change [L,R=301] to [P] as the reference of http://www.inmotionhosting.com/support/website/htaccess/redirect-without-changing-url site but it gives me following error
