+ * Adds auto-save capability to the TinyMCE text editor to rescue content
+ * inadvertently lost. This plugin was originally developed by Speednet
+ * and that project can be found here: http://code.google.com/p/tinyautosave/
+ *
+ * TECHNOLOGY DISCUSSION:
+ *
+ * The plugin attempts to use the most advanced features available in the current browser to save
+ * as much content as possible. There are a total of four different methods used to autosave the
+ * content. In order of preference, they are:
+ *
+ * 1. localStorage - A new feature of HTML 5, localStorage can store megabytes of data per domain
+ * on the client computer. Data stored in the localStorage area has no expiration date, so we must
+ * manage expiring the data ourselves. localStorage is fully supported by IE8, and it is supposed
+ * to be working in Firefox 3 and Safari 3.2, but in reality is is flaky in those browsers. As
+ * HTML 5 gets wider support, the AutoSave plugin will use it automatically. In Windows Vista/7,
+ * localStorage is stored in the following folder:
+ * C:\Users\[username]\AppData\Local\Microsoft\Internet Explorer\DOMStore\[tempFolder]
+ *
+ * 2. sessionStorage - A new feature of HTML 5, sessionStorage works similarly to localStorage,
+ * except it is designed to expire after a certain amount of time. Because the specification
+ * around expiration date/time is very loosely-described, it is preferrable to use locaStorage and
+ * manage the expiration ourselves. sessionStorage has similar storage characteristics to
+ * localStorage, although it seems to have better support by Firefox 3 at the moment. (That will
+ * certainly change as Firefox continues getting better at HTML 5 adoption.)
+ *
+ * 3. UserData - A very under-exploited feature of Microsoft Internet Explorer, UserData is a
+ * way to store up to 128K of data per "document", or up to 1MB of data per domain, on the client
+ * computer. The feature is available for IE 5+, which makes it available for every version of IE
+ * supported by TinyMCE. The content is persistent across browser restarts and expires on the
+ * date/time specified, just like a cookie. However, the data is not cleared when the user clears
+ * cookies on the browser, which makes it well-suited for rescuing autosaved content. UserData,
+ * like other Microsoft IE browser technologies, is implemented as a behavior attached to a
+ * specific DOM object, so in this case we attach the behavior to the same DOM element that the
+ * TinyMCE editor instance is attached to.
