Editing Magic cookie (section)

{{Short description|Type of data passed between programs}}

In [[computing]], a '''magic cookie''', or just '''cookie''' for short, is a token or short packet of data passed between communicating [[Computer program|programs]]. The cookie is often used to identify a particular [[Event (computing)|event]] or as "handle, transaction ID, or other token of agreement between cooperating programs".<ref>{{cite web |last=Raymond |first=Eric |title=Cookie |url=http://www.catb.org/~esr/jargon/html/C/cookie.html |work=The Jargon File |accessdate=2022-01-04|quote=A handle, transaction ID, or other token of agreement between cooperating programs. “I give him a packet, he gives me back a cookie.” The claim check you get from a dry-cleaning shop is a perfect mundane example of a cookie; the only thing it's useful for is to relate a later transaction to this one (so you get the same clothes back).}}</ref>
