You can also receive cookies from the server by reading the `"set-cookie"` headers in the response:

```elixir
iex(1)> response = HTTPoison.get!("http://httparrot.herokuapp.com/cookies/set?foo=1")
iex(1)> response = HTTPoison.get!("https://postman-echo.com/cookies/set?foo=1")

[{"Set-Cookie", "foo=1; Version=1; Path=/"}]
[ {"set-cookie", "foo=1; Path=/"}, ...]
