+# IMPORTANT NOTE:
+#
+# THIS FILE IS MAYBE JUST ONE OF MANY CONFIGURATION FILES IN THIS DIRECTORY.

+# LOOK FOR OTHER CONFIGURATION FILES! CHECK THE MANUAL AND INSTALLATION NOTES
+# (like README.Debian) FOR MORE DETAILS!
+#
+
+# This is a configuration file for apt-cacher-ng, a smart caching proxy for
+# software package downloads. It's supposed to be in a directory specified by
+# the -c option of apt-cacher-ng, see apt-cacher-ng(8) for details.
+# RULES:
+# - letter case in variable names does not matter
+# - names and values are separated by colon or equals sign
+# - for boolean variables, zero means false, non-zero means true
+# - "default value" means built-in (!) defaults, i.e. something which the
+#   program uses if the option is not set here or in other config files.
+#   That value might be explicitly mentioned in the description. Where it is
+#   not, there is no reason to assume any of the examples to be the default
+#   value! In doubt, use acngtool to query the value of the particular variable.
+
+# Storage directory for downloaded data and related maintenance activity.
+#
+# Note: When the value for CacheDir is changed, change the file
+# /lib/systemd/system/apt-cacher-ng.service too

+
+# TCP server port for incoming http (or HTTP proxy) connections.
+# Can be set to 9999 to emulate apt-proxy. Value of 0 turns off TCP server
+# (SocketPath must be set in this case).
+#
+# Port:3142
+
+# Addresses or hostnames to listen on. Multiple addresses must be separated by
+# spaces. Each entry must be an exact local address which is associated with a
+# local interface. DNS resolution is performed using getaddrinfo(3) for all
+# available protocols (IPv4, IPv6, ...). Using a protocol specific format will
+# create binding(s) only on protocol specific socket(s), e.g. 0.0.0.0 will
+# listen only to IPv4. The endpoint can also be specified as host:port (or
+# [ipv6-address]:port) which allows binding on non-standard ports (Port
+# directive is ignored in this case).

+# The following patterns are available for the purposes detailed, where

+# - «VFilePattern» for volatile data that may change like every hour. Files
+#   that match both PFilePattern and VfilePattern will be treated as volatile.
+# - Static data with file names that match VFilePattern may be overriden being
+#   treated as volatile by making it match the special static data pattern,
+#   «SPfilePattern».
+# - «SVfilePattern» or the "special volatile data" pattern is for the
+#   convenience of specifying any exceptions to matches with SPfilePattern,
+#   for cases where data must still be treated as volatile.
+# - «WfilePattern» specifies a "whitelist pattern" for the regular expiration
+#   job, telling it to keep the files even if they are not referenced by
+#   others, like crypto signatures with which clients begin their downloads.
+#
+# There are two versions. The pattern variables mentioned above should not be
+# set without good reason, because they would override the built-in defaults
+# (that might impact updates to future versions of apt-cacher-ng). There are
+# also versions of those patterns ending with Ex, which may be modified by the
+# local administrator. They are evaluated in addition to the regular patterns
+# at runtime.

+# file becomes identical to the *.bz2 file on the server which can be used by
+# APT when requesting a complete version of this file.
+# The downside of this feature is higher CPU load on the server during
+# the maintenance tasks, and the outcome might have not much value in a LAN

+#
+# FastTimeout = 4
+
+# Sometimes it makes sense to not store the data in cache and just return the
+# package data to client while it comes in. The following DontCache* parameters
+# can enable this behaviour for certain URL types. The tokens are extended
+# regular expressions which the URLs are evaluated against.
+#
+# DontCacheRequested is applied to the URL as it comes in from the client.
+# Example: exclude packages built with kernel-package for x86
+# DontCacheRequested: linux-.*_10\...\.Custo._i386
+# Example usecase: exclude popular private IP ranges from caching
+# DontCacheRequested: 192.168.0 ^10\..* 172.30
+#
+# DontCacheResolved is applied to URLs after mapping to the target server. If
+# multiple backend servers are specified then it's only matched against the
+# download link for the FIRST possible source (due to implementation limits).
+#
+# Example usecase: all Ubuntu stuff comes from a local mirror (specified as
+# backend), don't cache it again:
+# DontCacheResolved: ubuntumirror.local.net
+#
+# DontCache directive sets (overrides) both, DontCacheResolved and
+# DontCacheRequested.  Provided for convenience, see those directives for
+# details.
+#
+# Example:
+# DontCache: .*.local.university.int
+
+# Default permission set of freshly created files and directories, as octal
+# numbers (see chmod(1) for details).
+# Can by limited by the umask value (see umask(2) for details) if it's set in
+# the environment of the starting shell, e.g. in apt-cacher-ng init script or

+# based on /etc/mime.types, but without sorting, CGI execution, index page
+# redirection and other funny things.
+# To get this behavior, mappings between virtual directories and real
+# directories on the server must be defined with the LocalDirs directive.
+# Virtual and real directories are separated by spaces, multiple pairs are
+# separated by semi-colons. Real directories must be absolute paths.
+# NOTE: Since the names of that key directories share the same namespace as
+# repository names (see Remap-...) it is administrator's job to avoid conflicts

+# Usually the users are not allowed to specify custom TCP ports of remote

+#
+# AllowUserPorts: 80
+
+# Normally the HTTP redirection responses are forwarded to the original caller
+# (i.e. APT) which starts a new download attempt from the new URL. This
+# solution is ok for client configurations with proxy mode but doesn't work
+# well with configurations using URL prefixes in sources.list. To work around
+# this the server can restart its own download with a redirection URL,
+# configured with the following option. The downside is that this might be used
+# to circumvent download source policies by malicious users.
+# The RedirMax option specifies how many such redirects the server is allowed
+# to follow per request, 0 disables the internal redirection.
+# Default: guessed on startup, 0 if ForceManaged is used and 5 otherwise.
+#
+# RedirMax: 5
+
+# There some broken HTTP servers and proxy servers in the wild which don't
+# support the If-Range header correctly and return incorrect data when the
+# contents of a (volatile) file changed. Setting VfileUseRangeOps to zero
+# disables Range-based requests while retrieving volatile files, using

+# a negative value removes even If-Modified-Since headers.
+#
+# VfileUseRangeOps: 1
+
+# Allow data pass-through mode for certain hosts when requested by the client
+# using a CONNECT request. This is particularly useful to allow access to SSL

+# Examples:
+# PassThroughPattern: private-ppa\.launchpad\.net:443$

+
+# It's possible that an evil client requests a volatile file but does not
+# retrieve the response and keeps the connection effectively stuck over

+# Another way is to try to connect to the proxy first and detect a connection
+# timeout. The connection will then be made without HTTP proxy for the life

+# In mobile environments having an adhoc connection with a redirection to some
