# Sample configuration file for WANProxy XTech v3.0.5

# Codec definition must include following cache directives:
# - cache: Memory (default) or COSS (use persistent cache in disk)

# a proxy taking unencoded input and writing encoded output
# is considered to be a client.
#
# Only one proxy may be defined per instance. To host several proxies
# on the same node different processes must be launched each one with
# its own configuration.
# Any number of proxies can be defined in the same config file, and they will
# share the specified cache if using the same codec.
#
# Upon reception of SIGHUP the daemon will reread this file and apply the
# new values to any subsequent connections.
