Yea, I read that too, and it confused me. The reason that it confused me to
say that
"The get methods are rarely used" is because the get methods are then used 2
pages later.
(getCookies, getName & getValue)
If we are not supposed to get the cookies, what use is there to setting them
?
Maybe i'm missing something here...
Any light anyone (Jason???) could shine on this would be greatly
appreciated.

I thought I remembered reading something in Jason Hunter's Java
Servlet Programming book that was relevant here, and I just confirmed
it. On page 203, in the section on "Persistent Cookies", subsection
on "Working with Cookies", it says:
You can set a number of attributes for a cookie in addition to its
name and value. The following methods are used to set these
attributes. As you can see in Appendix B, HTTP Servlet API Quick
Reference, there is a corresponding get method for each set method.
The get methods are rarely used, however, because when a cookie is
sent to the server, it contains only its name, value, and version.
