Detecting Session Functionality And Redirecting

I want to redirect users who DO NOT SUPPORT sessions to another page.

Think this will work? PSEUDO CODE:

-------------------------------------------------------------------
<asp vbscript>
<session("test")="true">
<if session("test")="true" then do nothing else
response.redirect(www.domain.com/nosessions) end if>
-------------------------------------------------------------------

This is setting a session state of "true", and I presume if sessions are
disabled for security reasons, that the site will redirect accordingly?
