HTML5 Local Cache Localstorage and Sessionstorage methods of Operation Collection

Description

The Web Storage consists of two mechanisms as follows:

• sessionStorageMaintains a separate storage area for each given source (given origin), which is available during a page session (that is, as long as the browser is open, including page reload and recovery).
• localStorageThe same functionality, but the data still exists after the browser shuts down and then reopened.

Both of these mechanisms are Window.sessionStorage used by and Window.localStorage attributes (more specifically, objects are implemented in supported browsers and Window objects are WindowLocalStorage WindowSessionStorage hung localStorage under them and sessionStorage properties)--calling any of these objects creates an Storage object, by object, you can set, get, and remove data items. For each source (origin) sessionStorage and localStorage the use of different Storage objects--run and control independently.

For example, a call in a document localStorage would return an object, and the Storage call would sessionStorage return a different Storage object. These objects can be manipulated in the same way, but the operation is independent.
