ruby - How to completely stop the rails action from responding any kind of HTTP status? -


rails 3.2.13. jruby 1.7.15. ruby 1.9.3 interpreter

is there way kill rails action responding @ all? want avoid kind of response being sent anonymous hacker. there constraint check before index , if constraint check fails, index method ideally should stop responding. small part on rest api in effort kill action sending http status back.

any constructive suggestion welcomed.

i.e. 

def index   # kill method, not send response @ all. not 500 error end

thank help.

although rest api should send valid http response, can suppress output closing underlying output stream. exposed via rack's hijacking api (assuming server supports it):

def index   if env['rack.hijack?']     env['rack.hijack'].call     io = env['rack.hijack_io']     io.close   end end

this results in empty reply, i.e. server closes connection without sending data:

$ curl -v http://localhost:3000/ * connected localhost port 3000 > / http/1.1 > user-agent: curl/7.37.1 > host: localhost:3000 > accept: */* > * empty reply server * connection #0 host localhost left intact curl: (52) empty reply server
