What libcurl version on what operating system? Do you by any chance have a
public URL that provides a problematic stream?

This is pointless. libcurl uses this on its own.

This is confusing. CURLOPT_ENCODING will set the necessary headers. Adding
your own custom ones as well only risk to mess things up.

What? That's not a valid HTTP header. They must start with "[letters]:".

This is pointless.

This is just strange. It removes Authorization: headers, but libcurl doesn't
just randomly add any so there should be none to remove.
