Thanks Kyatric, i will study that method, but do you recommend do something like that?
As i said, i play many flash games and they need to download again after some days.
For example i played a lot of Kingdoms CCG on Kongregate.com, i dowloaded it once and played, than next day i played it again and don't need to download it, but on the next next day the game was not on cash and i needed to download it again...
Let's suppose that on HTML5 the game is cashed forever, but even so if i update the game, adding new features(new cards for example), the whole game will need to be downloaded again, right?
