文章摘要
这篇文章是一段Java代码，属于Servlet容器（J2EE）编写。代码定义了一个名为`IndexServlet`的类，实现`@WebServlet`注解，用于处理HTTP请求。该Servlet类中包含了两个方法：`getDo()`和`doPost()`，分别用于获取资源上下文路径和处理用户参数。
在`doPost()`方法中，代码检查了用户和密码参数是否为"1"，如果满足条件，则将用户身份信息设为session属性并重定向到"/success.jsp"；否则重定向回主页面。代码还使用了`HttpServletRequest`、`HttpServletResponse`、`HttpSession`等标准的Servlet API类。
文章简要介绍了该Servlet的核心逻辑和实现细节，展示了基本的用户验证和重定向功能。
