Overview#LocalStorage is part of W3C Web Storage
LocalStorage typically allows for up to 5MB of storage, although this can be increased at the user's discretion.
Data in LocalStorage isn't sent to the server as it is with cookies.
sessionStorage maintains a separate Web Storage area for each given origin that is available for the duration of the page session (as long as the browser is open, including page reloads and restores).
