type expires = [
| `Session
| `Max_age of int64
| `Date of Ptime.t
]

expires describes when a cookie will expire.

  • `Session - nothing will be set
  • `Max_age - Max-Age will be set with the number
  • `Date - Expires will be set with a date
type same_site = [
| `None
| `Strict
| `Lax
]
type value = string * string

The value of a cookie is a tuple of (name, value)

type t = {
expires : expires;
scope : Uri.t;
same_site : same_site;
secure : bool;
http_only : bool;
value : value;
}

Constructors

make

val make : ?expires:expires -> ?scope:Uri.t -> ?same_site:same_site -> ?secure:bool -> ?http_only:bool -> ?sign_with:Signer.t -> value -> t

make cookie creates a cookie with the key-value pair cookie

It will default to the following values:

Note that if no value is given for scope, the browsers might use a default value. For instance, if the cookie is set from the response of http://example.com/users/login and does not specify a scope, some browsers will use /users as a scope. If you want the cookie to be valid for every endpoint of your application, you need to use "/" as the scope of your cookie.

of_set_cookie_header ?signed_with ?origin header creates a cookie from a Set-Cookie header header.

If the header is not a valid Set-Cookie header, None is returned.
