This page detects your Internet Explorer version via navigator.userAgent and then hides the content that does not apply to your version. When parsing the userAgent, it looks for "MSIE 5", "MSIE 6", "MSIE 7", or "Trident 4" (Trident 4 is IE8, which sends "MSIE 8" in Standards mode and "MSIE 7" in Compatibility Mode). This page using inline JavaScript. The sample (attached) includes .js files and a separate content .htm file. Thanks to Jeremy for providing the sample and helping me tweak it to work with IE8.
