Every padawan knows these are the temptations of the dark side. :smiling_imp:

Just kidding.

"Cookies" are data chunks passed to your browser from a server and stored locally on your machine. Then, in subsequent requests to the same server, they are sent back along with the request data. This provides a mechanism to overcome the "stateless" nature of HTTP and provide context to subsequent communications. One common use of cookies is to retain user identification. Cookies can persist through different browser sessions.

The "Cache" is temporary storage in your browser of web resources like images, sound clips, and even entire pages. This allows the browser to respond much faster if the same resources are required again during the session. Unlike cookies, the cache is generally not stored for use between different sessions.
