Just a question: how may I tell "goth" library what proxy server it has to use?

[Bribon4]

I know this is not an issue but a 'feature request' or a 'how to' question.
I have an issue I can not address when using this gorgeous library.

I guess I should have to configure something like this:
proxyUrl, err := url.Parse("http://proxyIp:proxyPort")
myClient := &http.Client{
Transport: &http.Transport{
Proxy: http.ProxyURL(proxyUrl),
},
}

I don't know how to embed something like that inside a call from "goth" to "Azure" (por example).
When using "goth" I have no access to the http.Client instance variable it uses, hence I can not do anything like that.

My request may sound weird but, at the CPD I am working on, I can not trust one single proxy server, so when the one I am pointing to does not respond I need to point to other, on the fly. And for doing so I need the brick I am requesting.

Thanks in advance.
