Remove all headers from response when multiple headers are received

[hugochinchilla]

When a request is completed following a redirect, the curl response contains the headers from the first and the second requests. In this case not all the headers are removed, only the last one is stripped from the response, resulting in a body containing the other headers.

I'm sorry for duplicating the Issue, I did not know how the pull request+issue combo worked until now.
I'm closing this because #6 has the code attached
