Session Timeout Limit in ASP.NET?

Question

I'm amending a Session time out in the Web.Config for an ASP.NET application written in C# and currently I have the timeout set to 120 minutes as shown below:

<sessionState mode="InProc" cookieName="Application_SessionId" timeout="120"/>

Is there a limit to this value? So if for example I wished to set it to 24 hours (1440 minutes) would this be applied?

It's ASP.NET version 4.0 with MVC 2.0

Answer 1

by default the value is 20 and the maximum value is 525600 (525600 minutes equivalent to one year). Maintain below code in your Web.config file to maintain maximum session timeout:

<system.web>
    <sessionState mode="InProc" timeout="525600"></sessionState>
    ...
</system.web>

Above one worked for me. Please refer here
