Tags +# that are created based on client or server headers are +# evaluated later on and can overrule CLIENT-TAG and URL +# patterns! +# +# The tag is set for all requests that come from clients that +# requested it to be set. Note that "clients" are differentiated +# by IP address, if the IP address changes the tag has to be +# requested again. +# +# Clients can request tags to be set by using the CGI interface +# http://config.privoxy.org/client-tags. The specific tag +# description is only used on the web page and should be phrased +# in away that the user understand the effect of the tag. +# +# Examples: +# +# # Define a couple of tags, the described effect requires action sections +# # that are enabled based on CLIENT-TAG patterns. +# client-specific-tag circumvent-blocks Overrule blocks but do not affect other actions +# disable-content-filters Disable content-filters but do not affect other actions +# +# +# +# 6.17. client-tag-lifetime +# ========================== +# +# Specifies: +# +# How long a temporarily enabled tag remains enabled. +# +# Type of value: +# +# Time in seconds. +# +# Default value: +# +# 60 +# +# Notes: +# +# +-----------------------------------------------------+ +# | Warning | +# |-----------------------------------------------------| +# |This is an experimental feature. The syntax is likely| +# |to change in future versions. | +# +-----------------------------------------------------+ +# +# In case of some tags users may not want to enable them +# permanently, but only for a short amount of time, for example +# to circumvent a block that is the result of an overly-broad +# URL pattern. +# +# The CGI interface http://config.privoxy.org/client-tags +# therefore provides a "enable this tag temporarily" option. If +# it is used, the tag will be set until the client-tag-lifetime +# is over. +# +# Examples: +# +# # Increase the time to life for temporarily enabled tags to 3 minutes +# client-tag-lifetime 180 +# +# +# +# 6.18. trust-x-forwarded-for +# ============================ +# +# Specifies: +# +# Whether or not Privoxy should use IP addresses specified with +# the X-Forwarded-For header +# +# Type of value: +# +# 0 or one +# +# Default value: +# +# 0 +# +# Notes: +# +# +-----------------------------------------------------+ +# | Warning | +# |-----------------------------------------------------| +# |This is an experimental feature. The syntax is likely| +# |to change in future versions. | +# +-----------------------------------------------------+ +# +# If clients reach Privoxy through another proxy, for example a +# load balancer, Privoxy can't tell the client's IP address from +# the connection. If multiple clients use the same proxy, they +# will share the same client tag settings which is usually not +# desired. +# +# This option lets Privoxy use the X-Forwarded-For header value +# as client IP address. If the proxy sets the header, multiple +# clients using the same proxy do not share the same client tag +# settings. +# +# This option should only be enabled if Privoxy can only be +# reached through a proxy and if the proxy can be trusted to set +# the header correctly. It is recommended that ACL are used to +# make sure only trusted systems can reach Privoxy. +# +# If access to Privoxy isn't limited to trusted systems, this +# option would allow malicious clients to change the client tags +# for other clients or increase Privoxy's memory requirements by +# registering lots of client tag settings for clients that don't +# exist. +# +# Examples: +# +# # Allow systems that can reach Privoxy to provide the client +# # IP address with a X-Forwarded-For header. +# trust-x-forwarded-for 1 +# +# +# +# 6.19. receive-buffer-size +# ========================== +# +# Specifies: +# +# The size of the buffer Privoxy uses to receive data from the +# server. +# +# Type of value: +# +# Size in bytes +# +# Default value: +# +# 5000 +# +# Notes: +# +# Increasing the receive-buffer-size increases Privoxy's memory +# usage but can lower the number of context switches and thereby +# reduce the cpu usage and potentially increase the throughput. +# +# This is mostly relevant for fast network connections and large +# downloads that don't require filtering. +# +# Reducing the buffer size reduces the amount of memory Privoxy +# needs to handle the request but increases the number of +# systemcalls and may reduce the throughput. +# +# A dtrace command like: "sudo dtrace -n 'syscall::read:return / +# execname == "privoxy"/ { @[execname] = llquantize(arg0, 10, 0, +# 5, 20); @m = max(arg0)}'" can be used to properly tune the +# receive-buffer-size. On systems without dtrace, strace or +# truss may be used as less convenient alternatives. +# +# If the buffer is too large it will increase Privoxy's memory +# footprint without any benefit. As the memory is (currently) +# cleared before using it, a buffer that is too large can +# actually reduce the throughput. +# +# Examples: +# +# # Increase the receive buffer size +# receive-buffer-size 32768 +# +# +# +# 7. WINDOWS GUI OPTIONS +# ======================= +# +# Privoxy has a number of options specific to the Windows GUI +# interface: +# +# +# +# If "activity-animation" is set to 1, the Privoxy icon will animate +# when "Privoxy" is active. To turn off, set to 0. +# +#activity-animation 1 +# +# +# +# If "log-messages" is set to 1, Privoxy copies log messages to the +# console window. The log detail depends on the debug directive. +# +#log-messages 1 +# +# +# +# If "log-buffer-size" is set to 1, the size of the log buffer, i.e. +# the amount of memory used for the log messages displayed in the +# console window, will be limited to "log-max-lines" (see below). +# +# Warning: Setting this to 0 will result in the buffer to grow +# infinitely and eat up all your memory! +# +#log-buffer-size 1 +# +# +# +# log-max-lines is the maximum number of lines held in the log +# buffer. See above. +# +#log-max-lines 200 +# +# +# +# If "log-highlight-messages" is set to 1, Privoxy will highlight +# portions of the log messages with a bold-faced font: +# +#log-highlight-messages 1 +# +# +# +# The font used in the console window: +# +#log-font-name Comic Sans MS +# +# +# +# Font size used in the console window: +# +#log-font-size 8 +# +# +# +# "show-on-task-bar" controls whether or not Privoxy will appear as +# a button on the Task bar when minimized: +# +#show-on-task-bar 0 +# +# +# +# If "close-button-minimizes" is set to 1, the Windows close button +# will minimize Privoxy instead of closing the program (close with +# the exit option on the File menu). +# +#close-button-minimizes 1 +# +# +# +# The "hide-console" option is specific to the MS-Win console +# version of Privoxy.
