+## tinyproxy.conf -- tinyproxy daemon configuration file
+##
+## This example tinyproxy.conf file contains example settings
+## with explanations in comments. For decriptions of all
+## parameters, see the tinproxy.conf(5) manual page.
+##
+
+#
+# User/Group: This allows you to set the user and group that will be
+# used for tinyproxy after the initial binding to the port has been done
+# as the root user. Either the user or group name or the UID or GID
+# number may be used.
+#
+User root
+Group root
+
+#
+# Port: Specify the port which tinyproxy will listen on.  Please note
+# that should you choose to run on a port lower than 1024 you will need
+# to start tinyproxy using root.
+#
+Port 7700
+
+#
+# Listen: If you have multiple interfaces this allows you to bind to
+# only one. If this is commented out, tinyproxy will bind to all
+# interfaces present.
+#
+#Listen 192.168.0.1
+
+#
+# Bind: This allows you to specify which interface will be used for
+# outgoing connections.  This is useful for multi-home'd machines where
+# you want all traffic to appear outgoing from one particular interface.
+#
+#Bind 192.168.0.1
+
+#
+# BindSame: If enabled, tinyproxy will bind the outgoing connection to the
+# ip address of the incoming connection.
+#
+#BindSame yes
+
+#
+# Timeout: The maximum number of seconds of inactivity a connection is
+# allowed to have before it is closed by tinyproxy.
+#
+Timeout 600
+
+#
+# ErrorFile: Defines the HTML file to send when a given HTTP error
+# occurs.  You will probably need to customize the location to your
+# particular install.  The usual locations to check are:
+#   /usr/local/share/tinyproxy
+#   /usr/share/tinyproxy
+#   /etc/tinyproxy
+#
+#ErrorFile 404 "/usr/local/share/tinyproxy/404.html"
+#ErrorFile 400 "/usr/local/share/tinyproxy/400.html"
+#ErrorFile 503 "/usr/local/share/tinyproxy/503.html"
+#ErrorFile 403 "/usr/local/share/tinyproxy/403.html"
+#ErrorFile 408 "/usr/local/share/tinyproxy/408.html"
+
+#
+# DefaultErrorFile: The HTML file that gets sent if there is no
+# HTML file defined with an ErrorFile keyword for the HTTP error
+# that has occured.
+#
+DefaultErrorFile "/usr/local/share/tinyproxy/default.html"
+
+#
+# StatHost: This configures the host name or IP address that is treated
+# as the stat host: Whenever a request for this host is received,
+# Tinyproxy will return an internal statistics page instead of
+# forwarding the request to that host.  The default value of StatHost is
+# tinyproxy.stats.
+#
+#StatHost "tinyproxy.stats"
+#
+
+#
+# StatFile: The HTML file that gets sent when a request is made
+# for the stathost.  If this file doesn't exist a basic page is
+# hardcoded in tinyproxy.
+#
+StatFile "/usr/local/share/tinyproxy/stats.html"
+
+#
+# LogFile: Allows you to specify the location where information should
+# be logged to.  If you would prefer to log to syslog, then disable this
+# and enable the Syslog directive.  These directives are mutually
+# exclusive. If neither Syslog nor LogFile are specified, output goes
+# to stdout.
+#
+#LogFile "/usr/local/var/log/tinyproxy/tinyproxy.log"
+
+#
+# Syslog: Tell tinyproxy to use syslog instead of a logfile.  This
+# option must not be enabled if the Logfile directive is being used.
+# These two directives are mutually exclusive.
+#
+#Syslog On
+
+#
+# LogLevel: Warning
+#
+# Set the logging level. Allowed settings are:
+#	Critical	(least verbose)
+#	Error
+#	Warning
+#	Notice
+#	Connect		(to log connections without Info's noise)
+#	Info		(most verbose)
+#
+# The LogLevel logs from the set level and above. For example, if the
+# LogLevel was set to Warning, then all log messages from Warning to
+# Critical would be output, but Notice and below would be suppressed.
+#
+LogLevel Info
+
+#
+# PidFile: Write the PID of the main tinyproxy thread to this file so it
+# can be used for signalling purposes.
+# If not specified, no pidfile will be written.
+#
+#PidFile "/usr/local/var/run/tinyproxy/tinyproxy.pid"
+
+#
+# XTinyproxy: Tell Tinyproxy to include the X-Tinyproxy header, which
+# contains the client's IP address.
+#
+#XTinyproxy Yes
+
+#
+# Upstream:
+#
+# Turns on upstream proxy support.
+#
+# The upstream rules allow you to selectively route upstream connections
+# based on the host/domain of the site being accessed.
+#
+# Syntax: upstream type (user:pass@)ip:port ("domain")
+# Or:     upstream none "domain"
+# The parts in parens are optional.
+# Possible types are http, socks4, socks5, none
+#
+# For example:
+#  # connection to test domain goes through testproxy
+#  upstream http testproxy:8008 ".test.domain.invalid"
+#  upstream http testproxy:8008 ".our_testbed.example.com"
+#  upstream http testproxy:8008 "192.168.128.0/255.255.254.0"
+#
+#  # upstream proxy using basic authentication
+#  upstream http user:pass@testproxy:8008 ".test.domain.invalid"
+#
+#  # no upstream proxy for internal websites and unqualified hosts
+#  upstream none ".internal.example.com"
+#  upstream none "www.example.com"
+#  upstream none "10.0.0.0/8"
+#  upstream none "192.168.0.0/255.255.254.0"
+#  upstream none "."
+#
+#  # connection to these boxes go through their DMZ firewalls
+#  upstream http cust1_firewall:8008 "testbed_for_cust1"
+#  upstream http cust2_firewall:8008 "testbed_for_cust2"
+#
+#  # default upstream is internet firewall
+#  upstream http firewall.internal.example.com:80
+#
+# You may also use SOCKS4/SOCKS5 upstream proxies:
+#  upstream socks4 127.0.0.1:9050
+#  upstream socks5 socksproxy:1080
+#
+# The LAST matching rule wins the route decision.  As you can see, you
+# can use a host, or a domain:
+#  name     matches host exactly
+#  .name    matches any host in domain "name"
+#  .        matches any host with no domain (in 'empty' domain)
+#  IP/bits  matches network/mask
+#  IP/mask  matches network/mask
+#
+#Upstream http some.remote.proxy:port
+
+#
+# MaxClients: This is the absolute highest number of threads which will
+# be created. In other words, only MaxClients number of clients can be
+# connected at the same time.
+#
+MaxClients 100
+
+#
+# MinSpareServers/MaxSpareServers: These settings set the upper and
+# lower limit for the number of spare servers which should be available.
+#
+# If the number of spare servers falls below MinSpareServers then new
+# server processes will be spawned.  If the number of servers exceeds
+# MaxSpareServers then the extras will be killed off.
+#
+MinSpareServers 5
+MaxSpareServers 20
+
+#
+# StartServers: The number of servers to start initially.
+#
+StartServers 10
+
+#
+# MaxRequestsPerChild: The number of connections a thread will handle
+# before it is killed. In practise this should be set to 0, which
+# disables thread reaping. If you do notice problems with memory
+# leakage, then set this to something like 10000.
+#
+MaxRequestsPerChild 0
+
+#
+# Allow: Customization of authorization controls. If there are any
+# access control keywords then the default action is to DENY. Otherwise,
+# the default action is ALLOW.
+#
+# The order of the controls are important. All incoming connections are
+# tested against the controls based on order.
+#
+Allow 127.0.0.1
+
+# BasicAuth: HTTP "Basic Authentication" for accessing the proxy.
+# If there are any entries specified, access is only granted for authenticated
+# users.
+BasicAuth user password
+
+#
+# AddHeader: Adds the specified headers to outgoing HTTP requests that
+# Tinyproxy makes. Note that this option will not work for HTTPS
+# traffic, as Tinyproxy has no control over what headers are exchanged.
+#
+#AddHeader "X-My-Header" "Powered by Tinyproxy"
+
+#
+# ViaProxyName: The "Via" header is required by the HTTP RFC, but using
+# the real host name is a security concern.  If the following directive
+# is enabled, the string supplied will be used as the host name in the
+# Via header; otherwise, the server's host name will be used.
+#
+ViaProxyName "tinyproxy"
+
+#
+# DisableViaHeader: When this is set to yes, Tinyproxy does NOT add
+# the Via header to the requests. This virtually puts Tinyproxy into
+# stealth mode. Note that RFC 2616 requires proxies to set the Via
+# header, so by enabling this option, you break compliance.
+# Don't disable the Via header unless you know what you are doing...
+#
+#DisableViaHeader Yes
+
+#
+# Filter: This allows you to specify the location of the filter file.
+#
+#Filter "/usr/local/etc/tinyproxy/filter"
+
+#
+# FilterURLs: Filter based on URLs rather than domains.
+#
+#FilterURLs On
+
+#
+# FilterExtended: Use POSIX Extended regular expressions rather than
+# basic.
+#
+#FilterExtended On
+
+#
+# FilterCaseSensitive: Use case sensitive regular expressions.
+#
+#FilterCaseSensitive On
+
+#
+# FilterDefaultDeny: Change the default policy of the filtering system.
+# If this directive is commented out, or is set to "No" then the default
+# policy is to allow everything which is not specifically denied by the
+# filter file.
+#
+# However, by setting this directive to "Yes" the default policy becomes
+# to deny everything which is _not_ specifically allowed by the filter
+# file.
+#
+#FilterDefaultDeny Yes
+
+#
+# Anonymous: If an Anonymous keyword is present, then anonymous proxying
+# is enabled.  The headers listed are allowed through, while all others
+# are denied. If no Anonymous keyword is present, then all headers are
+# allowed through.  You must include quotes around the headers.
+#
+# Most sites require cookies to be enabled for them to work correctly, so
+# you will need to allow Cookies through if you access those sites.
+#
+#Anonymous "Host"
+#Anonymous "Authorization"
+#Anonymous "Cookie"
+
+#
+# ConnectPort: This is a list of ports allowed by tinyproxy when the
+# CONNECT method is used.  To disable the CONNECT method altogether, set
+# the value to 0.  If no ConnectPort line is found, all ports are
+# allowed.
+#
+# The following two ports are used by SSL.
+#
+ConnectPort 443
+#ConnectPort 563
+
+#
+# Configure one or more ReversePath directives to enable reverse proxy
+# support. With reverse proxying it's possible to make a number of
+# sites appear as if they were part of a single site.
+#
+# If you uncomment the following two directives and run tinyproxy
+# on your own computer at port 8888, you can access Google using
+# http://localhost:8888/google/ and Wired News using
+# http://localhost:8888/wired/news/. Neither will actually work
+# until you uncomment ReverseMagic as they use absolute linking.
+#
+#ReversePath "/google/"	"http://www.google.com/"
+#ReversePath "/wired/"	"http://www.wired.com/"
+
+#
+# When using tinyproxy as a reverse proxy, it is STRONGLY recommended
+# that the normal proxy is turned off by uncommenting the next directive.
+#
+#ReverseOnly Yes
+
+#
+# Use a cookie to track reverse proxy mappings. If you need to reverse
+# proxy sites which have absolute links you must uncomment this.
+#
+#ReverseMagic Yes
+
+#
+# The URL that's used to access this reverse proxy. The URL is used to
+# rewrite HTTP redirects so that they won't escape the proxy. If you
+# have a chain of reverse proxies, you'll need to put the outermost
+# URL here (the address which the end user types into his/her browser).
+#
+# If not set then no rewriting occurs.
+#
+#ReverseBaseURL "http://localhost:8888/"
