New Revision: 1556328
URL: http://svn.apache.org/r1556328
Log:
Refactor ServerCookie to separate cookie state from the helper code used to
generate the header. This change is purely a movement of code to improve
readability.
ServerCookie is now a pure data object holding MessageBytes, typically
resulting from the parse of the Cookie header done by Cookies.
The appendCookieValue static helper method is moved to a new class,
SetCookieSupport, that Response uses when addCookie is called.
