-/**
- *
- * Creates a cookie, a small amount of information sent by a servlet to
- * a Web browser, saved by the browser, and later sent back to the server.
- * A cookie's value can uniquely
- * identify a client, so cookies are commonly used for session management.
- *
- * <p>A cookie has a name, a single value, and optional attributes
- * such as a comment, path and domain qualifiers, a maximum age, and a
- * version number. Some Web browsers have bugs in how they handle the
- * optional attributes, so use them sparingly to improve the interoperability
- * of your servlets.
- *
- * <p>The servlet sends cookies to the browser by using the
- * {@link HttpServletResponse#addCookie} method, which adds
- * fields to HTTP response headers to send cookies to the
- * browser, one at a time. The browser is expected to
- * support 20 cookies for each Web server, 300 cookies total, and
- * may limit cookie size to 4 KB each.
- *
- * <p>The browser returns cookies to the servlet by adding
- * fields to HTTP request headers. Cookies can be retrieved
- * from a request by using the {@link HttpServletRequest#getCookies} method.
- * Several cookies might have the same name but different path attributes.
- *
- * <p>Cookies affect the caching of the Web pages that use them.
- * HTTP 1.0 does not cache pages that use cookies created with
- * this class. This class does not support the cache control
- * defined with HTTP 1.1.
- *
- * <p>This class supports both the Version 0 (by Netscape) and Version 1
- * (by RFC 2109) cookie specifications. By default, cookies are
- * created using Version 0 to ensure the best interoperability.
