37  * This class is a substitute for Cookies, but it is serializable.
38  * It is used to pass cookies back and forth when using RMI.
39  * Rather than pasing or returning a Cookie, which would cause a
40  * marshalling error, the Cookies are turned into SerializabeCookies,
41  * passed through RMI, then turned back into Cookies at the other end. <P>
42  *
43  * There is no reason why Cookies could not be serializable. Sun may well
44  * fix this oversight in version 2 of Java, in which case this class will
45  * no longer be necissary to use RMI with the MultiServer.
