Flash objects can be used by any flash file, so you could have an
"invisible" flash file reading values and doing something on a hybrid site.
Flash objects can be written/read at any time once the flash file has loaded
(to do the reading/writing as required).
Attached is a wrapper class I wrote to give easy access to read/write/delete
methods. It is comprised of static methods so you can do something like:
import LocalData;
// save record
LocalData.save("mysite", "lastUrl", "home.html");
.
.
.
// load it later
var last : String = LocalData.load("mysite", "lastUrl");
trace(last) // displays "home.html"
