Introduction The goal of COMPRESS is to reduce the bandwidth usage of NNTP. Compared to PPP compression [RFC1962] and modem-based compression ([MNP] and [V42bis]), COMPRESS offers greater compression efficiency. COMPRESS can be used together with Transport Layer Security (TLS) [RFC5246], Simple Authentication and Security Layer (SASL) encryption [RFC4422], Virtual Private Networks (VPNs), etc. The point of COMPRESS as an NNTP extension is to act as a compression layer, similar to a security layer like the one negotiated by STARTTLS [RFC4642]. Therefore, compression can be beneficial to all NNTP commands sent or received after the use of COMPRESS. ThisShow full document text
