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.
