rack-noie is the coolest rack middleware ever created. And it is so because it does everyone a favor: it shows the way out of your website to poor souls out there using Internet Explorer 6.
sudo gem install robworley-rack-noie -s http://gemcutter.org
just
require 'noie'
and
use Rack::NoIE, :redirect => '/noieplease.html'
the above will redirect to a page noieplease.html in your website. You can redirect to a URL as well, like so
use Rack::NoIE, :redirect => 'http://slashdot.org'
you can also define specific regex patterns or paths to redirect
use Rack::NoIE, :only => /^\/admin\//
or define specific regex patterns or paths as exceptions
use Rack::NoIE, :except => /^\/admin\//
use Rack::NoIE, :except => "/login"
use Rack::NoIE, :except => ["/home", "/login"]
or let the default kick in
use Rack::NoIE
I'm a nice guy. I'm so nice that the default URL points to Microsoft's IE8 upgrade page.
MIT, as usual.
