[support] Session variable and cache

[Bert Van Kets]

I'm sending the answer here for completeness.
Apparently the session variables are persistent in the database and 
that's why the animation was only shown once.
The solution is to use a module or theme preprocess function and pass 
the result of that to the page template. A timestamp variable can keep 
track if the animation has played or not.
