server-side javascript enabled detection

Is there a server-side way to detect if the client browser has javascript enabled??

I found an external component that does it, but it's not free...

I would like to detect JS status without external DLLs or components, just pure ASP: is this possible?

Thanks!

detection.html
=========
<html>
<head>
<meta http-equiv="refresh" content="1; URL=thepage.asp?script=no">
<script language="Javascript">
 window.location.href='thepage.asp?script=yes';
</script>
</head>
<body></body>
</html>


thepage.asp will have a querystring "script". yes means javascript enabled else not enabled.

I need the detection to happen before the <html> tag...

What if I can't create hidden fields or execute onload functions because the <html> tag has not yet be generated?

<%
Set browserdetect = Server.CreateObject("MSWC.BrowserType")
Response.Write("JavaScript: " & browserdetect.JavaScript)

sorry, scratch that... this will only tell you if the browser is JavaScript compatible, not if the user has it disabled.

How about using this?

<noscript>
<% Response.Write("You must have JavaScript enabled to use this form.") %>
</noscript>


 If you need to set a flag, swap out the "Response.Write" with something like this
<noscript>
<% session("bJavaScript") = FALSE %>
</noscript>

- or(redirect them to a non-javascript portion of the site) -

<noscript>
<% response.redirect=("no-javascript.asp") %>
</noscript>

In this way I can prevent users to log in if js is disabled... but what happens if they disable js status after logging in, while they're inside the application?

I should put a js check before every single piece of code...
