except for "private browsing" or "incognito" session
Data stored in localStorage is specific to the protocol of the page.
In particular, data stored by a script on a site accessed
with HTTP (e.g., http://example.com)
is put in a different localStorage object
from the same site accessed with HTTPS (e.g., https://example.com).
The keys and the values are always
in the UTF-16 DOMString format,
which uses two bytes per character.
As with objects, integer keys are automatically converted to strings.Copyright © 2021 Codeinu
