Hi
You migth visited macromedia.com and noticed that each time you reload the page you see a different flash animation.

How can this be done?
I want to show my visitors the main animation only the first time they arrive (a big one) and after that only show an small one.
Let's say that you arrive to the site for the first time. then "a.swf" will be shown. if you go deep in the site and come back to home (or visit the site again) you would get "b.swf".

Thanks for your help

one page load u read the users computer for your cookie.

if cookie found = old user = b.swf

else

write cookie show a.swf

you are looking for flash's Shared Object - like a cookie but for flash.
