Thank U
but what i attend to do is:
- swf resource is need, and there're a lot
- they're on the server first
- when loading swf needed, access loacally file first, if there's none, get remote swf resource from server
- after load from remote, cache swf files locally for the next application runs
How can this be done?
all the above happens by default unless a user clears their cache or has not browser cache- which you can't control.
I met sand box issue when I apply URLRequest api, and I've looked into game's on facebook and other SNS platform, caching is the
common way to build a game, there's a "loader.swf?v=XXXX" there, and if I copy it to file system and run it, surely it's doing URLLoading and trigger a sand box trouble like I do, but when it's applied in the browser, or say in the way it's originally used, it worked,
So I doubt there's something I can do to implement the goal I've imagined, question is, how ) ;
appending a changing query string (?v=XXX) to a url is a common way to prevent browser caching by making the browser think each of those swfs are different by virtue of the changing query string.
