Harrier

Harrier is a simple HTTPS proxy based on CONNECT tunneling technique with host-based filtering capabilities.

Install

With npm:

npm install harrier

Usage

Look at /examples folder. Usage is pretty straightforward:

var harrier = require('harrier')({
  blacklist: ['www.github.com']
});

var port = 8001;

harrier.listen(port, function() {
  console.log('Harrier is listening', port);
});

var harrier = require('harrier')(options)

Available options are:

• blacklist (array): an array of hosts that you want to block
• filter (function): a filtering function with function(host) signature. It will be cached and called on every request with the host parameter parsed from the CONNECT request as the only argument.

NOTE: You can specify only one option between blacklist and filter.

Test

npm test

Live testing

You can also do some live-testing with CLI tools like curl. For example, you can run the example above and then run:

curl 'https://www.github.com' -x 127.0.0.1:8001

You will see something like:

curl: (56) Proxy CONNECT aborted

If you try with a non-blacklisted url, you will see the HTML body, which basically means that the tunnel is correctly working.

Transparent proxing

You can't run this proxy transparently, so forget about routing HTTPS (SSL or TLS) packets with iptables to proxy's host/port.

Client must be aware of the proxy, otherwise they will NOT do the CONNECT tunnel.
