• A local SharedObject saves information permanently on the local file system (like cookies in a browser).
• However, local SharedObjects can store typed data such as numbers, objects, and functions.
• To create a new local SharedObject, we use the getLocal() method:

player1Info_so = SharedObject.getLocal("player1");

• If "player1" already exists, it is retrieved rather than created.
• We now assign custom properties to the built-in data property:

player1Info_so.data.highScore = 1200;

• The object is saved as an .sol file when:
  • the movie is closed
  • the flush() method is invoked
  • the SharedObject is deleted and garbage collected
• Once saved, the SharedObject can be retrieved later with the getLocal() method, exactly as it was created.
• By default, each domain can store up to 100kb of data on the user's computer.
• An example that tracks the total time a user has spent on a movie.

var userProfile_so = SharedObject.getLocal("userProfile");
trace(userProfile_so.data.totalVisitTime);
var then = 0;

this.onEnterFrame = function () {
  var now = getTimer();
  var frameTime = now - then;
  userProfile_so.data.totalVisitTime += frameTime;
  this.then = now;
}
