The encodeCookies Property

URL encoding of cookies is performed, if the encodeCookies property of the sun-web-app element in the sun-web.xml file is set to true. In Application Server 8, the default value of the encodeCookies property was true. This property was not present in Application Server 8. In Application Server 9.1 Update 1, the default value is false.

URL encoding of cookies is unnecessary. Setting this property to true is strongly discouraged. This property is provided only for those rare applications that depended on this behavior in Application Server 8.
