Ruby On Rails With Apache and mod_proxy using .htaccess

comechao (Tiago Bastos) — Thu, 31 May 2007 14:53:20 GMT

If you want your rails app in the same apache html directory, use a .htaccess like this :



RewriteEngine   on

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule     (.*) http://localhost:3000/$1 [P]

All resources that don't exist in your html directory will be requested ( using proxy) from mongrel.
