Session-only cookies
Preheat your oven people, for the time has come to thrust JavaScript
into it until some long term memory develops. In this tutorial, we'll look
up the recipe for session-only cookies, and how they can help your scripts
retain information even after the page is reloaded or cleared.

requests. When a site requiring login remembers your username on return
visits, for example, thank not Oreos, but these uneatable imposters.
There are two types of JavaSript cookies- permanent, and
session-only. The first one stores its information in a physical file
on the client's computer called "cookie.txt", with the stored data
"permanently" available. Session only cookies, on the other hand, stores
information in the browser memory, and is available for the duration of
the browser session. In other words, the data stored inside a session
cookie is available from the time of storage until the browser is closed.
Moving from page to page during this time does not erase the data.
This tutorial, as mentioned, focuses on session only cookies. Empty
your stomach as we dive into em'!
