Redirecting Flash page to non-flash page for other devices

I have a landing page which has flash.
Flash does not show up on other devices like mobile phones.
How to redirect the landing page with flash to a html page without flash for these devices?

I think you can use javascript to detect whether flash is enabled on the user’s browser, then if it isn’t, point the user to the html version.

You don’t need to redirect. Embed you swf using swfobject, and place alternate html content in the swfobject div

Thanks for the help.
@EastCoast: I will check this out. Adobe has given a full page brief about it at http://www.adobe.com/devnet/flashplayer/articles/alternative_content.html
