Rack::Redirect
Rack::Redirect, generic Rack redirect middleware.
By default to redirect requests based on path, but can be easily extended to match hostname, user-agent, or whatever might be available in the request.
Installation
Add this line to your application's Gemfile:
gem 'rack_redirect'And then execute:
$ bundle
Usage
Rackup
Add to config.ru:
require 'rack/redirect'
use Rack::Redirect, {
'/some/path' => '/new/path',
%r{^/profiles} => '/users'
}
use Rack::Redirect, {
'/home' => '/'
}, 301Rails
Add to config/application.rb (or any of the environment files):
config.middleware.insert_before 0, Rack::Redirect, {
'/some/path' => '/new/path',
%r{^/profiles} => '/users'
}
config.middleware.insert_before 0, Rack::Redirect, {
'/home' => '/'
}, 301Extending
To extend the functionality for e.g. user-agent detection, it's as simple as:
class UserAgentRedirect < Rack::Redirect
def request_matches?(request, pattern)
request.user_agent =~ pattern
end
end
use UserAgentRedirect, {
/iP(hone|od)/ => '/mobile'
}The pattern can actually be anything, so if you wan't use more variables in a single check, that's also possible:
class UserAgentAndPathRedirect < Rack::Redirect
def request_matches?(request, pattern)
request.user_agent =~ pattern[0] && request.path == pattern[1]
end
end
use UserAgentAndPathRedirect, {
[/iP(hone|od)/, '/mobile'] => '/iphone'
