Hello,
I try to migrating from Nginx to Caddy (0.10), But I dont find SSL options to keep the enable same features.
How to enable _Session resumption_ and _HSTS_ ?

Thanks
For HSTS you can do header / Strict-Transport-Security "max-age=31536000;", see the example here: https://caddyserver.com/docs/header
As for session resumption, it was talked about in this blog post: https://caddyserver.com/blog/caddy-0_8_3-released. I don't know much about this feature so I can't really comment further.
But FYI, questions like this should usually go on the forums if it's not an explicit issue: https://caddy.community/
I'm closing this, but feel free to continue discussing here 馃槃
You don't want session resumption by caching, it's not a great idea for servers to be storing that extra state anyway. If it gets compromised, every other client goes down with it. Session resumption by tickets is simpler and safer.
