I agree with all above msg-s, good webmaster could be able to make one code which would work for all browsers.
Answer of your question is
Code:
<script language="JavaScript"
type="text/JavaScript">
if(navigator.appName == "WebTV")
{
window.location = "WebTVHome.html"
}
if(navigator.appName == "Netscape")
{
window.location = "NetscapeHome.html"
}
if(navigator.appName == "Microsoft Internet Explorer")
{
window.location = "ExplorerHome.html"
}
window.location == "Other.html"
</script>
