Cookies are data that the server can leave at the client (browser). Clearly: 

A client arrives, asks the server for a page.


The server in the response headers can set cookies. For example, issuing two headers: Set-Cookie: foo = 123 and Set-Cookie: bar = baz - i.e. - "remember, foo - 123, and bar - baz".


At the next call the client, if he decided to remember, tells the server "Cookie: bar = baz; foo = 123. "



A session is something that allows you to distinguish one user from another, and usually stores this data somewhere. For example, remember an authorized user.
