How can I set automatically a proxy with credentials

Hallo Forum,

we wanna communicate with a server in the internet, but we are sitting
behind a proxy.

So our script does (not always!) fail to connect to the external server.

We then get this error:
C:/Ruby192/lib/ruby/1.9.1/net/http.rb:644:in `initialize': getaddrinfo:
No such host is known. (SocketError)

Unfortunately it is not a option for us to just set the proxy
environment variables.

The common environment variables http_proy etc are not set.
Firefox for example is configured to "Use proxy system setting".
IE uses a pac script to get the proxy server and uses the windows
credentials for authentication.

Is there somehow a way to get the "proxy system setting" with ruby like
the Firefox does?

I would really appreciate any help and sorry for my crappy English!

Steven
