From Google Chrome 80, they are planning to released from february, 2020, they will force SameSite=None for all Cookies if we want to use for third-party context. If no SameSite is set, then Chrome will understand as SameSite=Lax. It seems to be reversed the result as before (SameSite=None by default). Please see: https://www.chromium.org/updates/same-site
Therefore, we need to update our cookies with declarative setting SameSite from Playframework Controller.

Play Version (1.5.x / etc)

Playframework 1.5.x

Expected Behavior

1. Support SameSite enum inside the Http.Cookie
2. SameSite enum supports three values: Strict, Lax and None
