ences to the Safari browser as an indicator of the functional-
ity available within the HTML environment within AIR.
However, because the HTML engine is running in a run-

useful to understand before beginning development with
HTML and JavaScript within Adobe AIR.
Cookies
The Adobe Integrated Runtime has full support for setting

port is implemented via the operating system’s networking
stack. This means that AIR applications can share cookies set
by any browser or application that also leverage the operat-
