Cookie Util
From the site:
I have written a small utility class which I think some of you really would like to use. It is a small class that makes it possible to set Cookies via Actionscript without adding anything to the HTML Wrapper, all the code will be injected at runtime.

ObjectSerializer
From the site:
If anyone ever has the need to pass complex objects through a url, LocalConnection, or whatever.. I wrote an ObjectSerializer that you might want to use.
