Installing a http proxy cache like Polipo
can be advantageous in several ways. It makes internet access faster and has a filtering utility. As Polipo is only accessible from the machine on which it is installed, there is less security risk. The Polipo http proxy-cache can be installed in easy steps on a machine with a Linux operating system. Polipo also has a
separate DNS cache
and does not access the operating system cache to
retrieve DNS information
, but it can be configured to access other cache locations if required.
Installing a http proxy cache
can speed up internet access to a great extent.
Installing an HTTP proxy cache on your computer can bring several advantages:
It allows sharing of the Internet connection
The cache will display pages faster, even if you do not share your connection
It offers an optional filtering utility.
Polipo is an efficient and lightweight HTTP proxy cache.
sudo apt-get install polipo
Configure your software (e.g. web browser) to use
as the proxy.
Note that Polipo is accessible only from your machine, thus reducing security constraints.
Some of the configurable settings offered are:
Setting the memory and disk cache
Automatic filtering of HTTP headers such as user-agent, http-referer
URL filter Allowing hosts on the LAN to connect
If your LAN is 192.168.0.0/24 and your proxy server 192.168.0.1, edit the following file
and add the lines:
proxyAddress = "192.168.0.1"
allowedClients = 127.0.0.1, 192.168.0.0/24
Then type sudo
to take into account the new configuration.
Changing the port
To change the port on which Polipo listens, add the following proxyPort parameter to
proxyPort = 3128
Remember to use
sudo /etc/init.d/polipo restart
to apply changes.
Use a proxy server parent
If you want Polipo sends its own requests to another proxy, add the following parameter:
parentProxy = "squid.example.org: 3128"
Using an alternative DNS server
For enhanced performance, Polipo makes its own DNS resolutions without the use of the operating system.
It uses the DNS registered directly in
But you can request that Polipo use other DNS servers (e.g. to use OpenDNS). Simply add the following parameter:
dnsNameServer = 18.104.22.168, 22.214.171.124
If you are not using IPv6, add this parameter:
dnsQueryIPv6 = no
