How to handle requests for subdomains in a Rails application?

Question

Nginx

For example, I want my website URL to look like blog.mysite.com. How can I achieve this in Ruby on Rails? I am using nginx server.

Answer 1

You can, for example, write lines like this in the server section of the nginx configuration:

server {
...
    if ( $host != 'blog.mysite.com' ) {
        rewrite ^/(.*)$ http://blog.mysite.com/$1 permanent;
    }
...
}

For each subdomain, you need to create your own server section.
However, all these virtual hosts can even point to one Rail application. The application logic for each subdomain can be organized using the request.host variable .
