Is there a way to disable weak and medium ciphers suites for https, with the standalone Play Framework server?
Couldn't find anything about it.
The intention of the standalone server is not to deal with https traffic. The most common pattern is to use something like lighttpd, nginx or apache as a reverse proxy and offload the https processing to that.
Therefore, your question is more suited to whether it is possible to do what you need in one of the above http servers.
