Flash movies can be programmed to redirect to a different URL based on an event. I made a very simple swf (no graphics) and embedded it in html and it worked like a charm. I'm pretty sure that spiders can't watch movies and would probably not be redirected as they would just read the page, users with the flash plug in would be redirected to the content you want to show them and those without flash would get a rather ugly SE optimized page. Does anyone see any "holes" with this method?
Hi John Great idea! I wouldn't call it cloaking so much as a very clever way to redirect surfers. Holes? I'd say it is about the equivalent of a js redirect -- some humans will see your optimized page because they won't have the plug-in. There is also no protection from code thief. But those to problems may be worth living with for the simplicity of such a set up.
