Asp.net不允许多个用户登录 [英] Asp.net does not allow more than one user logged in

问题描述

您好，



我在IIS 8.5上运行了2个应用程序。这两个应用程序都需要身份验证对于身份验证，我使用了身份数据模型。当我从调试器运行应用程序时，我没有问题，当时登录多个用户。



当我将它们带到IIS时，应用程序不允许当时更多的是一个用户，他们将用户重定向到登录页面（没有错误消息）。如果我重新启动IIS，应用程序允许多用户一段时间，然后他们不会。



我正在使用.NET framework 4.5.2



我在服务器的事件查看器上收到此警告：

异常信息：
异常类型：HttpException 
异常消息：在发送HTTP标头后，服务器无法追加标头。

谢谢你提前。



我尝试过的事情：



1。检查代码是否有错误

2.重新启动IIS

3.重新启动服务器（Windows Server 2012 R2）

4.升级OWIN但是OWIN Cookies 3.1不起作用，所以我将它再次降级为3.0.1

解决方案

如果其他人面临类似的问题，这是解决方案。

Hello,

I have 2 applications running on IIS 8.5. Both of the applications need authentication. For the Authentication I used the Identity Data Model. When I run the applications from the debugger I have no problem login more than one user at the time.

When I take them to the IIS the applications don't allow more that one user at the time and they keep redirect users to login page (no error message). If I restart the IIS the applications allow multiusers for a while and then they don't.

I'm using .NET framework 4.5.2

I'm getting this warning on server's event viewer:

Exception information: 
    Exception type: HttpException 
    Exception message: Server cannot append header after HTTP headers have been sent.

Any kind of help would be appreciated.

Thank you in advance.

What I have tried:

1. Checked the code for errors
2. Restarted IIS
3. Restarted the server (Windows Server 2012 R2)
4. Upgraded OWIN but OWIN Cookies 3.1 didn't work so I downgraded it again to 3.0.1
