Please enable Travis CI to prevent regressions like the current one in 2af00d7:

--- FAIL: TestDeleteCookies (0.00s)

It passed the tests as you can see in https://travis-ci.org/ahmetb/go-httpbin/builds/210435220

This test succeeds with go 1.7.5 and fails with 1.8. The test is actually wrong; it sets three cookies, deletes two, then checks to see if all three remain.

[ahmetb]

We don't just check if all 3 exists. We check that 2 are unset (to empty value), 1 is modified but all 3 are present. Since it worked this way with go1.7 just fine, I've reason to believe that either the CookieJar implementation or the http.Client's way of dealing with cookies has changed.

[dbenque]

For a cookie defined like this:
http.Cookie{ Name: "k1", Value: "", Path: "/", Expires: time.Unix(0, 0), MaxAge: 0, }

Go 1.7 produce the following string:
k1=; Path=/

While Go 1.9 produce the following string:
k1=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT

This is due to the following fix golang/go@d86a6ef

So now in 1.9 you have a real deletion of the cookie thanks to the expiration time that is correctly set.
