Property key constant Type of value Required Description
NSHTTPCookieComment NSString NO Comment for the cookie. Only valid for version 1 cookies and later. Default is nil.
NSHTTPCookieCommentURL NSURL or NSString NO Comment URL for the cookie. Only valid for version 1 cookies and later. Default is nil.
NSHTTPCookieDomain NSString Special, a value for either NSHTTPCookieOriginURL or NSHTTPCookieDomain must be specified. Domain for the cookie. Inferred from the value for NSHTTPCookieOriginURL if not provided.
NSHTTPCookieDiscard NSString NO A string stating whether the cookie should be discarded at the end of the session. String value must be either "TRUE" or "FALSE". Default is "FALSE", unless this is cookie is version 1 or greater and a value for NSHTTPCookieMaximumAge is not specified, in which case it is assumed "TRUE".
NSHTTPCookieExpires NSDate or NSString NO Expiration date for the cookie. Used only for version 0 cookies. Ignored for version 1 or greater.
NSHTTPCookieMaximumAge NSString NO A string containing an integer value stating how long in seconds the cookie should be kept, at most. Only valid for version 1 cookies and later. Default is "0".
NSHTTPCookieName NSString YES Name of the cookie
NSHTTPCookieOriginURL NSURL or NSString Special, a value for either NSHTTPCookieOriginURL or NSHTTPCookieDomain must be specified. URL that set this cookie. Used as default for other fields as noted.
NSHTTPCookiePath NSString NO Path for the cookie. Inferred from the value for NSHTTPCookieOriginURL if not provided. Default is "/".
NSHTTPCookiePort NSString NO comma-separated integer values specifying the ports for the cookie. Only valid for version 1 cookies and later. Default is empty string ("").
NSHTTPCookieSecure NSString NO A string stating whether the cookie should be transmitted only over secure channels. String value must be either "TRUE" or "FALSE". Default is "FALSE".
NSHTTPCookieValue NSString YES Value of the cookie
NSHTTPCookieVersion NSString NO Specifies the version of the cookie. Must be either "0" or "1". Default is "0".
