Persistent client side storage

• Session and global storage

• Keys are strings; values are storage items

• Big security issues

interface Storage {
  readonly attribute unsigned long length;
  DOMString key(in unsigned long index);
  StorageItem getItem(in DOMString key);
  void setItem(in DOMString key, in DOMString data);
  void removeItem(in DOMString key);
};

interface StorageItem {
    attribute boolean secure;
    attribute DOMString value;
};
