My goal is when user requests root (AND ONLY ROOT, other pages work fine) with something like:
http://domain.com/////
http://domain.com//////////////
http://domain.com//
app should 301 redirect user to one and only correct:
http://domain.com/
I'm using Webrick, rack-rewrite gem and planning to host it on Heroku. Please remember that i'm new in Rails.
UPDATE ======
Rails: redirect all unknown routes to root_url — this is totally different problem. They just redirect all unknown hosts to root. I have 404 working normally.
My problem is that any amount of slashes works as homepage and URL has all of those slashes. I'm doing it for SEO to get rid of duplicates of homepage. I want it to work like here: http://netpeak.ua (try "netpeak.ua////////", you will be redirected to "netpeak.ua").
UPDATE 2 - added content of routes.rb ======
Rails.application.routes.draw do
resources :questions
resources :feedbacks
devise_for :users
get '' => 'public#index'
get '/agency' => 'public#about'
get '/contact' => 'public#contact'
get '/uslugi' => 'services#index'
get '/portfolio' => 'projects#index'
get '/uslugi/:id' => 'services#show'
get '/portfolio/:id' => 'projects#show'
resources :articles, param: :id
resources :settings, as: 'home' #home so it doesn't go to another page
namespace :admin do
resources :articles, :users, :projects, :services, :feedbacks, :questions
get '' => 'projects#index'
get 'contact' => 'settings#contact'
get 'feedback' => 'settings#feedback'
get 'fininfo' => 'settings#fininfo'
get 'calls' => 'settings#calls'
get 'orders' => 'settings#orders'
get 'letters' => 'settings#letters'
get 'allquestions' => 'settings#allquestions'
get 'projectsettings' => 'settings#projectsettings'
get 'servicessettings' => 'settings#servicessettings'
get 'aboutsettings' => 'settings#aboutsettings'
get 'startpagesettings' => 'settings#startpagesettings'
patch 'contact' => 'settings#update'
patch 'feedback' => 'settings#update'
patch 'fininfo' => 'settings#update'
patch 'projectsettings' => 'settings#update'
patch 'servicessettings' => 'settings#update'
patch 'aboutsettings' => 'settings#update'
patch 'startpagesettings' => 'settings#update'
end
end
