Cookies!

The term ‘cookie’ shall be familiar not only to programmers, but also to many of the more conscious, ordinary computer users. I’m not, unfortunately, talking about sweet pastry, but HTTP cookies.

Those cookies that we all know and love (if we’re web developers) or hate (if we’re overly paranoid about privacy) are not the only thing in computing to be known under this name, however. I learned this quite recently when talking to a friend of mine who is working in the realm of IT security. As it turns out, ‘cookie’ can refer to quite diverse array of different solutions, all unified through similar underlying concept.
