Some of the systems that I need to get access to from programs are not available via the web proxy….but others are only available using the web proxy.  So I needed a way to turn the proxy on and off depending on which system I needed to connect to.  I did some digging around and came up with the following code:

require 'win32/registry'

def proxy_disable
   reg = Win32::Registry::HKEY_CURRENT_USER.open("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\",
             Win32::Registry::KEY_WRITE)
   reg.write("ProxyEnable", Win32::Registry::REG_DWORD, 0)
end

def proxy_enable
   reg = Win32::Registry::HKEY_CURRENT_USER.open("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\",
             Win32::Registry::KEY_WRITE)
   reg.write("ProxyEnable", Win32::Registry::REG_DWORD, 1)
end
...
ie = Watir::IE.new
ie.goto("http://website_via_proxy.com/")
proxy_disable()
ie.goto("http://website_direct.com/")
proxy_enable()

You can also modify the proxy server by writing to “ProxyServer”, and change the exceptions list by writing to “ProxyOverride”.
