Accept cookise in an HTTP request sent by the server

curl -i "http://httpbin.org/cookies/set?name=Foo+Bar"

In this request we asked the httpbin server to send us a cookie (normally this is the decision of the server, but the httpbin server is here to help us).

Output (showing only the header part) where we can see the row Set-Cookie, that is setting a cookie in our "broswer".
