cookies are just set of name and
string value pair. You definitely can put more than one cookie, but you have to set it one by one in
jsp. Here is some notes from netscape about cookie specs.
Multiple Set-Cookie headers can be issued in a single server response.
Instances of the same path and name will overwrite each other, with the latest instance taking precedence. Instances of the same path but different names will add additional mappings.
However there are limitations: 4 kilobytes per cookie, 20 cookies per server or domain.
Hope this answers your question
