Defines a set of flags that you can assign to a cookie in the HTTP cookie jar by calling the SetCookie method or query from the HTTP cookie jar by calling the GetCookie method.

Syntax

typedef enum _XHR_COOKIE_FLAG {
  XHR_COOKIE_IS_SECURE = 0x1,
  XHR_COOKIE_IS_SESSION = 0x2,
  XHR_COOKIE_THIRD_PARTY = 0x10,
  XHR_COOKIE_PROMPT_REQUIRED = 0x20,

} XHR_COOKIE_FLAG;

Constants

 
XHR_COOKIE_IS_SECURE
Value: 0x1
The cookie is secure.

When this flag is set, the client is only to return the cookie in subsequent requests if those requests use HTTPS.
XHR_COOKIE_IS_SESSION
Value: 0x2
The cookie is only usable in the current HTTP session and is not persisted or saved.
XHR_COOKIE_THIRD_PARTY
Value: 0x10
The cookie being set is a third-party cookie.
XHR_COOKIE_PROMPT_REQUIRED
Value: 0x20
A prompt to the user is required to accept the cookie from the server.
XHR_COOKIE_EVALUATE_P3P
Value: 0x40
The cookie has a Platform-for-Privacy-Protection (P3P) header.
XHR_COOKIE_APPLY_P3P
Value: 0x80
A cookie with a Platform-for-Privacy-Protection (P3P) header has been applied.
XHR_COOKIE_P3P_ENABLED
Value: 0x100
A cookie with a Platform-for-Privacy-Protection (P3P) header has been enabled.
XHR_COOKIE_IS_RESTRICTED
Value: 0x200
The cookie being set is associated with an untrusted site.
XHR_COOKIE_IE6
Value: 0x400
XHR_COOKIE_IS_LEGACY
Value: 0x800
XHR_COOKIE_NON_SCRIPT
Value: 0x1000
Does not allow a script or other active content to access this cookie.
XHR_COOKIE_HTTPONLY
Value: 0x2000
Enables the retrieval of cookies that are marked as "HTTPOnly".

Do not use this flag if you expose a scriptable interface, because this has security implications. If you expose a scriptable interface, you can become an attack vector for cross-site scripting attacks. It is imperative that you use this flag only if they can guarantee that you will never permit third-party code to set a cookie using this flag by way of an extensibility mechanism you provide.
