Updated story wont load in browser unless I first clear temporary

If I update a storyline file and then re-publish with the same filename as the old version my browser remembers the old version of the story i.e. it has cached certain pages.

Similarly when testing a recent story built from a free template I noticed that if I started playing the story and then closed the browser - when I re-open the story and reload the story I am not able to start from the beginning - the browser returns to that point in the story where I had previously stopped.

Is there anyway to stop this from happening other than clearing the cache in the browser manually each time?

Thanks
