定义 进入正题前，我们先以一个典型场景来引出本文的主角。 如果把网站或 APP 比喻成一个商场，那互联网用户的行为就如同逛街的顾客，他们从商场任意一扇门进入，然后东逛逛西瞅瞅，有的意兴阑珊很快就离开了商场，有的兴致不错买了一些商品后才离开。 对于商场而言，顾客一系列的行为是一次来访，同理，对于网站或 APP 来说，用户一系列的行为，也是一次访问。 市面上，类似的定义，我们就称之为 Session 或 Visit。 意义 用户行为往往是单点发生的，即在什么时间什么地点干了一件什么样的事，也就是我们熟知的4W1H模型： Who：谁 When：时间 Where：地点 How：如何 What：具体事件 基于这样用户角度的行为记录，无论是一个商场，还是一个网站或 APP ，就可以知道他们的用户都具体干了些什么事情，比如什么时间进入，什么时间买了什么东西等等。 但是，还有一类需求，单点记录的方式并不能很好的满足，比如： 用户平均会来几次？ 每次平均逛了几个页面？ 每次来平均待多久？ 某个具体页面用户平均停留多长时间？ 可以发现，类似需求，都需要把用户单点发生的行为串联起来形成一个整体，并在此基础上进行计算后才能得到。 这样的连续行为整体，就是我们已定义好的 Session 概念，而解决类似的分析需求正是 Session 之于用户行为分析最大的意义。 组成 铺垫完 Session 的定义和意义后

1. 在server.xml中定义context时采用如下定义 <Context path="/livsorder" docBase="/home/httpd/html/livsorder" defaultSessionTimeOut="3600" isWARExpanded="true" isWARValidated="false" isInvokerEnabled="true" isWorkDirPersistent="false"/> 2. 在web.xml中通过参数指定： 30 其中30表示30分钟 <session-config> <session-timeout>30</session-timeout> </session-config> 3. 在程序中通过servlet api直接修改 HttpSession ses = request.getSession(); ses.setMaxInactiveInterval(10); 设置单位为秒，设置为-1永不过期。 来源： https://www.cnblogs.com/webcc/archive/2012/05/29/2523698.html

There are a few things I keep in sessions like username, userID, email, etc. I allow the user to stay logged into the website by setting a long expiration date on the authentication cookie. So it's very common for the session to expire while the user is still authenticated. The problem I am running into is that sometimes the user's session times out but they're still authenticated. So for example, one of my user pages (which requires authentication) will say "Welcome Mike" when their
