What is the default session timeout value in ASP.NET?

asp.net Solutions

Solution 1 - asp.net

It is 20 Minutes according to MSDN

From MSDN:

>Optional TimeSpan attribute. > >Specifies the number of minutes a session can be idle before it is abandoned. The timeout attribute cannot be set to a value that is greater than 525,601 minutes (1 year) for the in-process and state-server modes. The session timeout configuration setting applies only to ASP.NET pages. Changing the session timeout value does not affect the session time-out for ASP pages. Similarly, changing the session time-out for ASP pages does not affect the session time-out for ASP.NET pages. The default is 20 minutes.

Solution 2 - asp.net

It depends on either the configuration or programmatic change.
Therefore the most reliable way to check the current value is at runtime via code.

See the HttpSessionState.Timeout property; default value is 20 minutes.

You can access this propery in ASP.NET via HttpContext:

this.HttpContext.Session.Timeout // ASP.NET MVC controller
Page.Session.Timeout // ASP.NET Web Forms code-behind
HttpContext.Current.Session.Timeout // Elsewhere
