I’ve tried searching the site already, but this issue is somewhat too specific for the answer’s I’ve found.

I would like to include via CSS/HTML/JavaScript on my web-page, a way to detect if someone is not using IE 8 or equal (Firefox, Safari, etc.) and redirecting them to a page that tells them to download IE 8. Ideally this method would detect any CSS compatible browser, however, if it’s too difficult to do that...I would settle with just being able to detect if the user is using IE 7 or older, and requesting that they download IE 8 on a separate page.

I ultimately would not like them to view the page unless they have IE8 or equal.

I hope this makes sense.

Any ideas?

Thank You,
D

On the client side you can use conditional compilation to detect the IE version. Use the following in a JavaScript block:

isIE8=@cc_on @_jscript_version == 5.8 ? true : false;
isIE7=@cc_on @_jscript_version == 5.7 ? true : false;
isIE6=@cc_on @_jscript_version == 5.6 ? true : false;
isIE55=@cc_on @_jscript_version == 5.5 ? true : false;

This requires JavaScript. To force a page not to be displayed unless then have IE you should do the check on the server side. This can be done by checking the user agent.

That will correctly force IE8 to render your site in IE8 mode,

<!--[if lt IE 7]>
<
script type="src/JavaScript">
add a javascript here that will redirect your page
</script>
<![endif]-->

This should work.
