# Configuration specific to AS registration. Unless other marked, all fields
# are *REQUIRED*.
homeserver:
  # The URL to the home server for client-server API calls, also used to form the
  # media URLs as displayed in bridged IRC channels:
  url: "http://localhost:8008"
  #
  # The URL of the homeserver hosting media files. This is only used to transform
  # mxc URIs to http URIs when bridging m.room.[file|image] events. Optional. By
  # default, this is the homeserver URL, specified above.
  #
  # media_url: "http://media.repo:8008"

  # Drop Matrix messages which are older than this number of seconds, according to
  # the event's origin_server_ts.
  # If the bridge is down for a while, the homeserver will attempt to send all missed
  # events on reconnection. These events may be hours old, which can be confusing to
  # IRC users if they are then bridged. This option allows these old messages to be
  # dropped.
  # CAUTION: This is a very coarse heuristic. Federated homeservers may have different
  # clock times and hence produce different origin_server_ts values, which may be old
  # enough to cause *all* events from the homeserver to be dropped.
