Problem Statement
Session times out before session timeout value
In many cases where the website/ application sessions time out before the set session timeout value, we can resolve such issues by enabling the 32-bit applications option from IIS.
Solution
1. Open the IIS Manager.
2. Locate the Application Pool used by the website/ application in question.
3. Right-click on the application pool name, Advanced Settings.
Enable the 32-bit applications option to TRUE.
