Attention!!! Firefox will default to two more private properties, but all start with "_"
if (Cookies.hasownproperty (i) && I.indexof ("_")! = 0) {

When you write the cache separately for IE, you can use the scope of the IE Userdata,ie UserData in the document that is in the same directory as the current document
