title: Redirect users to a message page when accessed through IE7
body: <p>I am using ruby on rails 3 for my site and am almost finished, the site is due to go live very soon (Monday) but I am having problems with IE7 compatability, so as a temporary measure I would like to have users redirected to a "404" esque page if they are using IE7, it will just have some basic info stating to try another browser for now until the issues are fixed</p>
  
  <p>How would i go about this in rails 3? Has anyone done anything like this in the past? I dont want to get into the should I/shouldnt I support IE7, I am going to, just going to take a little longer than I thought</p>
  
  <p>Any help on this appreciated</p>
