Yes - this is done with a shim.swf - it is quite simple
You create a shim ( 5x5 or 1 x 1 example) swf movie with a
GetURL("http://redirecthere.com";) action in it.

On the page you set a meta tag
  <META HTTP-EQUIV="Refresh" CONTENT="10; URL=sendmeHere.html">

The shim movie is tiny so won't effect any design, and can be placed 
anywhere - and it certainly will load faster than 10 seconds and forward 
people to a flash enabled page - if that doesn't happen - the meta tag 
takes place.

So if flash is present - the action happens prior to the meta.

P.S. - not fool proof or ideal for all situations. Also - becomes a bit 
more complicated for sub version checking
