[akka-http] adding cookie attributes

[Christophe Pache]

Hello everyone!

I'm trying to add a sameSite attribute to cookies using the scaladsl and it looks like the Cookie API is quite closed. What I would like to do is something like 

`Set-Cookie: key=value; HttpOnly; SameSite=strict`

My feeling is that the only current way to do so is to craft a header with something like 

`RawHeader("Set-Cookie", "key=value; HttpOnly; SameSite=strict")`

If so, what about adding attributes to cookie header?

Thanks for any comment on that! Have a nice akking day!

Hi Christophe,

yes, that's correct. There seems to be no way to model custom cookie attributes right now. Using RawHeader is the right workaround for now. I filed https://github.com/akka/akka-http/issues/1354 to discuss improvements.
