* There is no VALUE option since the Servlet specification does not permit the creation of a Cookie with a name
* that is either null or the zero length string.
*
* The historical intention (from the user agent perspective) of using a name-value-pair without an equals sign has
* been to indicate a cookie with a name but no value. Tomcat has done the opposite. The current RFC6265bis text
* treats a name-value-pair without an equals sign as a cookie with a value but no name. Supporting this will
* require changes to the Servlet specifcation.
