This document enables a pair of communicating proxies to reuse a
congestion-controlled connection between themselves for sending
requests in the forwards and backwards direction.  Because the
connection is essentially aliased for requests going in the backwards
direction, reuse is predicated upon both the communicating endpoints
authenticating themselves using X.509 certificates through Transport
Layer Security (TLS).  For this reason, we only consider connection
reuse for TLS over TCP and TLS over Stream Control Transmission
Protocol (SCTP).  This document also provides guidelines on
connection reuse and virtual SIP servers and the interaction of
connection reuse and DNS SRV lookups in SIP.  [STANDARDS TRACK]
