# gofer configuration file

# Address for the control/debug server.
# DO NOT EXPOSE THIS TO THE INTERNET, it is dangerous and will leak a lot of
# information.
control_addr: "127.0.0.1:8081"

# Request logging.
reqlog:
  # Name of the log; just an id used to refer to it on the server entries
  # below.
  "requests.log":
    # Path to the log file.
    file: "/var/log/gofer/requests.log"

    # How many entries to hold in memory. Defaults to 0 (synchronous logging).
    bufsize: 16

    # Log format.
    # Known formats: <common>, <combined>, <combinedvh>, <lighttpd>, <gofer>
    # (that is the default).

# IP rate limiting.
ratelimit:
  # Name of the IP rate limit arena; just an id used to refer to it on the
  # server entries below.
  "rl-arena1":
    # Rate to enforce.
    # Format is "requests/period". For example, "50/1s" will allow 50
    # requests every second.
    rate: "50/1s"

    # How many IPs to hold in memory, to keep the memory usage bounded.
    # Setting this to 1000 will increase memory usage by ~128 KiB.
    # Default: 1000.
    #size: 1000

    # By default, IPv6 addresses get limited at /64, /56 and /48
    # simultaneously; and the rate for /64 is the one given above, for /56 is
    # 4x the /64 rate, and /48 is 8x the /64 rate.
    # This is an imperfect heuristic to account for the fact that IPv6 is
    # allocated to end users in different block sizes, and it is not possible
    # to tell them apart.
    # You can configure custom rates for each one as follows:
    #rate64: "50/1s"
    #rate56: "200/500ms"
    #rate48: "400/250ms"

        # template that can refer to submatches as $1, $2, etc.
        # By default, a 307 (temporary redirect) is used. You can change it by
