How to determine http status code in range error handler

Question

What I'd like to do is:

error 400..510 do
    {:'400' => 'Bad Request', :'401' => ...}[<http-status-code>.to_s.to_sym]
end

where <http-status-code> is some expression, evaluated to error code to be returned. One possible way the handler is triggered:

get '/test' do
    401
end

Is this achievable?

If you want achieve different behaviours, why you don't simply catch each status code with `error 400 do`, `error 401 do` ... ? — Sir l33tname, Nov 17 '13 at 14:58
That's what I did. But I hoped it could be done with less code... — x-yuri, Nov 17 '13 at 16:19

You can send a Net::HTTP request. The output of that request will be a Net::HTTPResponse object. For example, from the Ruby Net::HTTP documentation at http://ruby-doc.org/stdlib-2.0.0/libdoc/net/http/rdoc/Net/HTTP.html:

uri = URI('http://example.com/index.html')
res = Net::HTTP.get_response(uri)
res.code

You must be getting me wrong. I'm trying to determine status code of _current request_. And if you're suggesting to make subrequest to determine status code, that would be overkill. (I've slightly updated the question.) – x-yuri Nov 16 '13 at 18:33
