Redirect users to a message page when accessed through IE7

Question

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

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

Any help on this appreciated

Answer 1

You could do a script to redirect:

<!--[if IE 7]>
  <script type="text/javascript">
    window.location = "http://www.google.com/";
  </script>
<![endif]-->

Or a html:

<!--[if IE 7]>
  <meta http-equiv="REFRESH" content="0;url=http://www.google.com/">
<![endif]-->

Or simply leave a message saying that this site don't support

If you are able to use jQuery, you can do a simple browser version test and then redirect to the appropriate page and set a cookie:

   //IE 7 browser detection
    if ($.browser.msie) {
        var version = $.browser.version;

        if (version == '7.0') {
            var cookie = $.cookie('IE7');

            if (cookie != 'set') {
                $.cookie('IE7', 'set');

                window.location = '404-url-string';

            }

            window.location = '404-url-string';

        }
    }

you will need to bring in the jquery cookie plugin as well to set the cookie. The '404-url-string' would be the pathname of the page you are directing to.
