I understand the passing of parameters and how cookies are used for session management, but how are user-defined header values useful??
HFSJ Ch4 introduces the addHeader("foo", "bar") and setHeader() methods, but does not discuss their practical use!

setHeader might be used if you need to control stuff like cache.
response.setHeader("Cache-Control","no-store"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
