Description:

dc_client runs a client proxy to provide access to a remote cache
server (typically over TCP/IPv4) by providing a local service
(typically over unix domain sockets). It starts listening on a
configurable network address for connections and establishes a
persistent connection to an instance of dc_server for proxying
cache operations to. Incoming connections are expected to
communicate using the distcache protocol, and would typically
be applications using one of the distcache APIs in libdistcache to
encapsulate these communications.

The common use of dc_client is to run as a local agent on each
host machine that requires use of the distributed cache, as the
listening address should probably use unix domain sockets which
are better suited to frequent (and temporary) connections being
used for individual cache operations. Likewise, the connection
dc_client makes to the cache server (dc_server) for proxying cache
operations is typically over a genuine network to remote machine,
using TCP/IPv4.
