[Javascript] Flash Detection

[Terry]

if you are working with a server-side language with session handling you can
use this process:

on entrance page:
open a new window, flashcheck. whatever size, could even be hidden if you
want.

on flashcheck (2 items):
plays a swf that only has a redirect to a page, flashset
Meta refresh, i usually set it for 6 secs, that redirects to flashno

on flashset:
set hasflash session var to 1
self.close

on flashno:
self.close

if you dont have session handling, use cookies.  the key is in flashcheck.
you can do similar to check for JS.
