 * String domain - domain to match
 * String path - path to match
 * Boolean secure - access is secure (ssl generally)

     turns input into a Cookie (singleton if given a Cookie)
     the `request_domain` argument is used to default the domain if it is not explicit in the cookie string 
     the `request_path` argument is used to set the path if it is not explicit in a cookie String.
 
     explicit domains/paths will cascade, implied domains/paths must *exactly* match (see http://en.wikipedia.org/wiki/HTTP_cookie#Domain_and_Pat)

-* Cookie setCookie(cookie, request_domain, request_path) - add a cookie to the jar
-* Cookie[] setCookies(cookiestr_or_list, request_domain, request_path) - add a large number of cookies to the jar
+* Cookie setCookie(cookie, request_domain, request_path) - modify (or add if not already-existing) a cookie to the jar
+* Cookie[] setCookies(cookiestr_or_list, request_domain, request_path) - modify (or add if not already-existing) a large number of cookies to the jar
 * Cookie getCookie(cookie_name,access_info) - get a cookie with the name and access_info matching
 * Cookie[] getCookies(access_info) - grab all cookies matching this access_info
