[PATCH 2/6] http: handle proxy proactive authentication

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If http_proactive_auth flag is set and there is a username
but no password in the proxy url, then interactively ask for
the password.

This makes possible to not have the password written down in
http_proxy env var or in http.proxy config option.

Also take care that CURLOPT_PROXY don't include username or
password, as we now set them in the new set_proxy_auth() function
where we use their specific cURL options.
