ActionController::RoutingError: No route matches [CONNECT] "/"

Hi,

i’ve been getting the subject error for some while in production.
I’ve tried to find out what that connect even means with little avail.
But i was generally surprised how much hacking attempts are being made,
so
i’m pretty sure it’s ill intent.

Just, i can’t seems to get rid of the error. I tried to add rescue_from
to
my ApplicationController, as in:

rescue_from ActionController::RoutingError, with: :error_404

but that doesn’t do it. The call goes from phusion through rack and
rails,
and ends in
actionpack-4.2.5/lib/action_dispatch/middleware/debug_exceptions.rb:21:in
`call’

Has anyone encountered this in the wild ?

CONNECT is an http method used for proxies to allow tunnelling arbitrary
traffic through a proxy: basically someone has been scanning for
misconfigured proxies (and probably other stuff too). Just a fact of
life really.

This type of routing error can’t be rescued like that since rails
doesn’t know which controller should be used. If it bothers you then you
could try blocking it at the webserver level (eg
https://httpd.apache.org/docs/2.4/mod/core.html#limit)

Thanks Fred,

strange to think there should be an error that can’t be handled in rails. Still,
thanks for the answer, which i am unfortunately not sure i understand.

You could also handle via a rack middleware or by supplying a custom
exception app (see
http://guides.rubyonrails.org/configuring.html#rails-general-configuration)

Are you saying i should have a

Not sure - never done this, but this seems to be the mechanism Apache
provides for filtering requests based on http method.
