If configured, the store would automatically pick up cookies from responses and add them to requests. Also, it would make sure that the security rules about which cookies to apply in which situations would be applied.

This is part of the bigger initiative to support a high-level HTTP client interface as tracked as #16856.

Investigating if other libraries do this. This is starting to become pretty web-browser-ish.

My research indicates WS does not do this => we probably shouldn't as well (at least not as a first thing to jump on unless people start demanding it furiously).

@ktoso it's is very useful to write deep web(behind forms) crawlers.

As low as JDK does this https://docs.oracle.com/javase/7/docs/api/java/net/CookieManager.html
Some web API (such as Wikipedia - https://phabricator.wikimedia.org/T124252) require non-basic cookie handling

val newCookies = response.headers.filter(_.isInstanceOf[`Set-Cookie`]).map { v =>
  val cookie = v.asInstanceOf[SetCookie].cookie()
  HttpCookiePair.apply(cookie.name(), cookie.value())
}
val cookie = Cookie(newCookies)

Gentlemen, is there elegant way of constructing Cookie header out of Set-Cookie headers ? Currently I have to cast to java SetCookie in order to get raw value. Scala version returns rendered value with path from value(). Is there right way to do it ? I'm on 2.4.4

Anywhere:

response.header[`Set-Cookie`]

Routing DSL:

headerValue[`Set-Cookie`] { setCookie => 

}

Oh, it's not routing DSL. I'm making client call.

That's why I've shown both examples :) see "anywhere"

I see. response.header[Set-Cookie] returns only first header though. It would be nice to have response.headers[Set-Cookie]

Fun idea, I fear we can't just add it like that though because name already used, some helper might be a fun idea, please open a ticket.

For now it's: val setCookies = response.headers.collect { case c: Set-Cookie => c }
