SWFObject redirectUrl not functional with ExpressInstall

How do you specify a redirect URL for the adobe flash express install? I'm using swfobject 2.2, and while I thought MMredirectURL in the flashvars might be what I needed, this just doesn't work. I also tried setting redirectUrl in the attributes o开发者_如何学编程bject before embedding the swf, but this doesn't work either.

What is the proper way to specify a redirect URL to go through after the Express Install occurs with swfobject 2.2?

I have no idea, but here's a workaround. Set a cookie before the user leaves the page, and if they come to the same page WITH that cookie, perform a manual redirect. It's ugly, but it works.
