Also known as: no-archive header
A header a poster could add, set to yes, asking archiving services not to retain the article beyond its normal expiry on news servers. Compliance was always voluntary: large archives honoured it, private mirrors and search sites often did not. Because copies propagate to thousands of servers within seconds, the header never guaranteed disappearance, and text quoted into replies survived regardless.
