Use subdomain string as a part of redirection url #80

Open gabyshev opened 8 years ago

I'm not sure. Is there a way to get the current subdomain before redirecting?

For example: request url:

abc.mysite.com/audio/song.mp3

And I want it to be redirected here

mysite.com/abc/audio/song.mp3

maybe something like:

r301 %r{^(/audio/(.*)}, lambda { |match, rack_env|
  subdomain = rack_env['SERVER_NAME'].split('.')[0]
  "http://mysite.com/#{subdomain}/audio/#{match[1]}"
}
