Lighttpd's FastCGI Environment

[bones <boesemar@googlemail.com>]

I am porting my application from ruby fcgi to rack which is in
production using the Lighttpd webserver.

I noticed that lighttpd doesn't send PATH_INFO or QUERY_STRING so I
used to patch it by reconstructing it from REQUEST_URI. Now with Rack
I have exactly the same situation. Rack::Request.GET is empty. This
fix on the environment makes it working:

class RackApp

  def fix_env(ec)
       if (ec['PATH_INFO'].to_s.empty?) then
          pi =  ec['REQUEST_URI']
          pi = pi[0..(pi.index('?')-1)] if pi.include?('?')
          ec['PATH_INFO'] = pi
       end

       if (ec['QUERY_STRING'].to_s.empty?) then
          ec['QUERY_STRING'] = ec['REQUEST_URI'].include?('?') ?
              ec['REQUEST_URI'].scan(/.?\?(.*)/)[0][0] :
              ""
       end
       ec
  end

 def call(env)
    Rack::Request.new(fix_env(env))
   # [...]
  end
end


As far as I know Lighttpd and Rails (which used Rack?!) is a popular
combination - so I am quiet surprised that I don't find anything
related on the web. Especially - shouldn't that be implemented into
Rack's CGI/FastCGI Handler?
