本文整理了Java中javax.servlet.http.HttpSession.isNew()方法的一些代码示例，展示了HttpSession.isNew()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。HttpSession.isNew()方法的具体详情如下：
包路径：javax.servlet.http.HttpSession
类名称：HttpSession
方法名：isNew

HttpSession.isNew介绍

[英]Returns true if the client does not yet know about the session or if the client chooses not to join the session. For example, if the server used only cookie-based sessions, and the client had disabled the use of cookies, then a session would be new on each request.
[中]如果客户端尚不知道该会话，或者如果客户端选择不加入该会话，则返回true。例如，如果服务器仅使用基于cookie的会话，而客户端已禁用cookie的使用，则每个请求都会有一个新的会话。
