use some Middleware only for specific Rack website

Question

I have a Rack server where I run multiple websites.

use Rack::Session::Cookie

app = lambda do |env|

  case

  # Kek Mobile
  when env[\'HTTP_HOST\'] =~ /mobi.k         


        

Answer 1

I believe the URLMap middleware will solve your problem, or at least put you on the right track.

• Examples: http://blog.ninjahideout.com/posts/rack-urlmap-and-kicking-ass
• Official docs: http://rack.rubyforge.org/doc/classes/Rack/URLMap.html

As you can see, URLMap lets you supply a different middleware pipeline for each app:

use Rack::Lint

map "/" do
  use Rack::CommonLogger
  run our_test_app
end

map "/lobster" do
  use Rack::ShowExceptions
  run Rack::Lobster.new
end

From your example, it's clear that this will not work directly, since you are mapping based on the HTTP host. However, the official docs mention, "Support for HTTP/1.1 host names exists if the URLs start with http:// or https://." So, perhaps you can call map "http://mobi.kek.com" and map "http://fb.kek.com".

Good luck!
