This KSS plugin adds support for localStorage and sessionStorage. It provides the parameter provider methods localVar and sessionVar and the actions setLocalVar, setSessionVar, delLocalVar and delSessionVar. It can be used in much the same way as stateVar and setStateVar. This plugin does not work with IE6/7 (that could be changed by implementing the userDataBehavior).
