In my site i have a welcome animation (created with jquery) which runs when any one opens my website (**www.mysite.com**). Then the same user going to anther page in my site for example **www.mysite.com/about** then click back to home (**www.mysite.com**) the animation again shows up. How can i restrict this ?

Share some logic like putting a session or settimeout or something like that.
