NNTP Protocol Overview
The Network News Transfer Protocol (NNTP) is documented in
RFC 977. NNTP
is a request-reply protocol in the style of SMTP or FTP.
Unlike mail, news does not require separate protocols for user-to-host
and host-to-host exchanges. NNTP is used in all cases. NNTP
has facilities to support reading newsgroups, posting new articles,
and transferring articles between news servers.
