--- sidebar_label: CookieSourceScheme --- # CookieSourceScheme type Represents the source scheme of the origin that originally set the cookie. A value of "Unset" allows protocol clients to emulate legacy cookie scope for the scheme. This is a temporary ability and it will be removed in the future. #### Signature: ```typescript export type CookieSourceScheme = 'Unset' | 'NonSecure' | 'Secure'; ```
