应用程序在多个选项卡中打开时注销问题

我正在面对我的MVC5应用程序中的注销问题。



如果我打开标签1，完成我们的工作并保持打开，然后打开标签2并继续在标签2中工作15分钟，标签1将返回到登录页面，因为自动注销（在web.config中15分钟内设置超时）。


$ b $下面的b是web.config配置

I am facing the log out issue in my MVC5 application.

if I am opening tab 1, finish our work and leave it open, then open tab two and continue working in tab two for 15 minutes, tab one will return to the log in page due to automatically logout(Timeout set in 15 minutes in web.config).

below are the web.config configuration

<system.web>
    <httpCookies httpOnlyCookies="true" />
    <customErrors mode="On">
      <error statusCode="500" redirect="~/Error/InternalServer" />

      <error statusCode="403" redirect="~/Error/BadRequest" />
      <error statusCode="401" redirect="~/Unauthorised/Index" />
    
    <caching>
      <outputCache enableOutputCache="false" enableFragmentCache="false" />
