/**
 * Parses the Set-Cookie value into an array of <tt>Cookie</tt>s.
 *
 * <p>Syntax of the Set-Cookie HTTP Response Header:</p>
 *
 * <p>This is the format a CGI script would use to add to
 * the HTTP headers a new piece of data which is to be stored by
 * the client for later retrieval.</p>
 *
 * <PRE>
 *  Set-Cookie: NAME=VALUE; expires=DATE; path=PATH; domain=DOMAIN_NAME; secure
 * </PRE>
 *
 * <p>Please note that Netscape draft specification does not fully
 * conform to the HTTP header format. Netscape draft does not specify
 * whether multiple cookies may be sent in one header. Hence, comma
 * character may be present in unquoted cookie value or unquoted
 * parameter value.</p>
