Ruby mechanize over SSH tunnel Socks5 proxy?

Question

I'm trying to get mechanize to go over a SSH tunnel SOCKS5 proxy. Some reason it keeps getting an error during the HTTP requests. Like it's getting an EOF before it should. If I turn off the proxy setting it works, I'm not sure why it would be receiving multiple connection requests from the proxy.

What might cause multiple requests to be sent back? No other traffic is going over the tunnel.

require 'rubygems'
require 'mechanize'
require 'logger'
require 'pp'

a = Mechanize.new { |agent|
    agent.user_agent_alias = 'Windows Mozilla'
    agent.log = Logger.new $stdout
    agent.agent.http.debug_output = $stdout
    agent.set_proxy 'localhost', 9999
}

page = a.get('http://www.whatsmyip.org')
PP.pp(page)

Output:

Answer 1

You should be using a http proxy.

If you really want to use a socks5 proxy you could look into socksify.
