Also known as: CHECK, TAKETHIS
The streaming transfer pair. CHECK asks a peer whether it wants an article by Message-ID; TAKETHIS sends the article immediately without waiting for an answer, letting the receiver reject it afterwards. Because a feeder can pipeline hundreds of these down one connection, throughput no longer depends on round-trip time. Together they carry most inter-server traffic on the modern backbone.
