[Stop the animation when a user goes back to the home from an internal page]

Hi Everybody,

 

I'm new here. First of all I'd like to congratulate with you all and with the developers of GSAP. 

I set up a timeline that runs on anytime the homepage loads. Do you know if there is a way to stop the animation when a user goes back to the home by clicking on the logo (from an internal page)?

I would like that the timeline starts only when the user lands from an external link o when he types the url in the browser.

 

Thanks to all in advance!
