Rack-newbie: how do i interrupt rack stack processing?

Rack-newbie: how do i interrupt rack stack processing?

[Dan]

Hello,

Currently I'm composing my very first rack-based application and after
few unsuccessful (unqualified) web searches decided to ask for
support.

My app looks like:

require '...'

use Rack::ContentLength
use My::Filter2
use My::Filter1
use My::HTTPHeaderValidator

app = Proc.new {...}

run app

Can I return response to client from `My::HTTPHeaderValidator' (in
case of unacceptable headers received) and bypass (or interrupt
execution of) My::Filter2, My::Filter3 and others?

Just move My::HTTPHeaderValidator to the top of the stack :)

It works! :)

Just to clarify. In case I need to stop my app walk through stack I
should not inquire @app.call, right?

Yep, that's correct :-)
