Yummy JSON Cookies (using Prototype)

Updated to v.3: CookieJar now uses only prototype.js 1.5.1. See changes

JavaScript code to store data as JSON strings in cookies. It uses prototype.js 1.5.1 and json.js to store and retrieve JSON data from cookies.

Now we can store and retrieve JavaScript Objects, Arrays, Boolean, String, Number values using cookies, just like storing Java Objects in session on the server side.

Works with Firefox 1.5, 2.0, IE 6.0 and Opera 9.10.
