ASP.NET会话超时太早 [英] ASP.NET Session Timeouts too early

问题描述

我想，当身份验证的用户创建一个新的会话创建日志，但由于某些原因，我碰到的奇怪的行为。为了测试设置我的会话超时2分钟在web.config中：

I'm trying to create a log when an authenticated user creates a new session, but for some reason I've run into odd behavior. For testing I set my Session timeout to 2 minutes in web.config:

<sessionState cookieName="AppName_SessionId" timeout="2" />   

而在Global.asax.vb我有以下的code登录：

And in Global.asax.vb I have the following code to log:

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)

   If My.User.IsAuthenticated = True Then
      Log.Create()
   End If
End Sub

一切工作正常后，我登录，关闭浏览器，然后重新打开。它只记录一次，而我访问过的网页，而我在会议上我。问题是，当我停下来，让会议为止（2分钟测试），然后再试一次。它记录新的会话，这是我期望的行为，但随后在session_start上每个页面视图下焙烧。我证实了这一点在不同的浏览器。

Everything works correctly after I login, close the browser and reopen it. It only logs once while I visit pages while I'm in the session. The problem is when I stop and let the session expire (2 minutes for testing) and try again. It logs the new session, which is the behavior I expect, but then the Session_Start is fired on every page view thereafter. I confirmed this on different browsers.

看来，一旦会话已过期，浏览器仍然是开放的，它无法维持会话。

It appears that once the session has expired and the browser is still open, that it cannot maintain the session.

推荐答案

我的修复是什么添加到会话：

My fix was to add something to the Session:

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs) 

   If My.User.IsAuthenticated = True Then 
      Log.Create() 
      Session("SessionLogged") = True
   End If 

End Sub
