I'm trying to route watir through a proxy pragmatically -- this means within the script I'd like to change my proxy dynamically before launching the browser.

Here's what I've tried so far (and so far am failing): I'm running chrome and lucid lynx ubuntu. I chose TREX cause I thought watir might be making use of PROXY or something.

I rewrote /usr/bin/google-chrome as:

#!/bin/bash
/opt/google/chrome/chrome --proxy-server="$TREX" $@

The reason I'm passing in the environment variable to proxy-server rather than http_proxy is because I never could get http_proxy to work as is anyways

then I did a simple:

require 'rubygems'
require 'watir-webdriver'

ENV['TREX'] = "XX.XX.XX.XX:YY"
browser = Watir::Browser.new(:chrome)
browser.goto("http://mysite.com")

Anyways, what is happening here is that it is forwarding me to the login page of the proxy rather than just forwarding the request.

What am I missing here? I feel like I'm pretty close.
