Кеширующий Web Proxy polipo…

$ nano /etc/polipo/config

### Basic configuration
### *******************

logSyslog = true
logFile = /var/log/polipo/polipo.log

# Uncomment one of these if you want to allow remote clients to
# connect:

#proxyAddress = «::99»        # both IPv4 and IPv6
# proxyAddress = «0.0.0.0»    # IPv4 only

proxyAddress = «127.0.0.1»
proxyPort = 8123

# If you do that, you'll want to restrict the set of hosts allowed to
# connect:

# allowedClients = «127.0.0.1, 134.157.168.57»
# allowedClients = «127.0.0.1, 134.157.168.0/24»

allowedClients = 127.0.0.1
allowedPorts = 1-65535

# Uncomment this if you want your Polipo to identify itself by
# something else than the host name:

proxyName = «localhost»

# Uncomment this if there's only one user using this instance of Polipo:

cacheIsShared = false

# Uncomment this if you want to use a parent proxy:

#parentProxy = «127.0.0.1:8118»

# Uncomment this if you want to use a parent SOCKS proxy:

#socksParentProxy = «localhost:9050»
#socksProxyType = socks5

### Memory
### ******

# Uncomment this if you want Polipo to use a ridiculously small amount
# of memory (a hundred C-64 worth or so):

# chunkHighMark = 819200
# objectHighMark = 128

# Uncomment this if you've got plenty of memory:

# chunkHighMark = 50331648
# objectHighMark = 16384

chunkHighMark = 67108864

### On-disk data
### ************

# Uncomment this if you want to disable the on-disk cache:

#diskCacheRoot = «/var/cache/polipo»
diskCacheRoot = «»

diskCacheTruncateTime = 7d
diskCacheUnlinkTime =15d
diskCacheTruncateSize = 128 MB

# Uncomment this if you want to put the on-disk cache in a
# non-standard location:

#diskCacheRoot = «»

# Uncomment this if you want to disable the local web server:

localDocumentRoot = «»

# Uncomment this if you want to enable the pages under /polipo/index?
# and /polipo/servers?.  This is a serious privacy leak if your proxy
# is shared.

# disableIndexing = false
# disableServersList = false

disableLocalInterface = true
disableConfiguration = true

### Domain Name System
### ******************

# Uncomment this if you want to contact IPv4 hosts only (and make DNS
# queries somewhat faster):
#
#dnsQueryIPv6 = no

# Uncomment this if you want Polipo to prefer IPv4 to IPv6 for
# double-stack hosts:
#
dnsQueryIPv6 = reluctantly

# Uncomment this to disable Polipo's DNS resolver and use the system's
# default resolver instead.  If you do that, Polipo will freeze during
# every DNS query:

dnsUseGethostbyname = yes

### HTTP
### ****

# Uncomment this if you want to enable detection of proxy loops.
# This will cause your hostname (or whatever you put into proxyName
# above) to be included in every request:

disableVia = true

# Uncomment this if you want to slightly reduce the amount of
# information that you leak about yourself:

# censoredHeaders = from, accept-language
# censorReferer = maybe

censoredHeaders = from,accept-language,x-pad,link
censorReferer = maybe

# Uncomment this if you're paranoid.  This will break a lot of sites,
# though:

# censoredHeaders = set-cookie, cookie, cookie2, from, accept-language
# censorReferer = true

# Uncomment this if you want to use Poor Man's Multiplexing; increase
# the sizes if you're on a fast line.  They should each amount to a few
# seconds' worth of transfer; if pmmSize is small, you'll want
# pmmFirstSize to be larger.

# Note that PMM is somewhat unreliable.

# pmmFirstSize = 16384
# pmmSize = 8192

# Uncomment this if your user-agent does something reasonable with
# Warning headers (most don't):

# relaxTransparency = maybe

# Uncomment this if you never want to revalidate instances for which
# data is available (this is not a good idea):

# relaxTransparency = yes

# Uncomment this if you have no network:

# proxyOffline = yes

# Uncomment this if you want to avoid revalidating instances with a
# Vary header (this is not a good idea):

# mindlesslyCacheVary = true

# Suggestions from Incognito configuration
maxConnectionAge = 3m
maxConnectionRequests = 100
serverMaxSlots = 16
serverSlots = 2
tunnelAllowedPorts = 1-65535
dnsMaxTimeout=30
dontCacheCookies = true

В privoxy устанавливаем перенаправление локально:

# Polipo
forward    /  127.0.0.1:8123

$ /usr/local/etc/rc.d/privoxy restart
$ /usr/local/etc/rc.d/polipo restart

Если используем socks:

$ sockstat -4 | grep polipo
