let pp = function
| Ok cookie -> Format.printf "%a\n" Http_cookie.pp cookie
| Error err -> Format.printf "Err: %s" err

HTTP Cookie header value:

# let s = "SID=234234asdasdasda" in
  let c = List.nth (Http_cookie.of_cookie s |> Result.get_ok) 0 in
  let s1 = Http_cookie.to_cookie c in
  s = s1 ;;
- : bool = true

HTTP Set-Cookie header value:

# let s = "SID=31d4d96e407aad42; Path=/; Domain=ffff::0234:ddd:192.168.0.1; Expires=Sun, 06 Nov 1994 08:49:37 GMT; Secure; HttpOnly" in
  let c = Http_cookie.of_set_cookie s |> Result.get_ok in
  let s2 = Http_cookie.to_set_cookie c in
  s = s2;;
- : bool = true

Create HTTP cookie:

# Http_cookie.create ~path:"/home" ~domain:"eee:aaa:abdf::223:192.168.0.1" ~secure:true ~same_site:`Strict ~name:"SID" "31d4d96e407aad42" |> pp;;
