sessionState Timeout

Hey,

Hope you're keeping well.

In ASP.NET, the sessionState timeout in web.config defines the inactivity period in minutes before a session expires, but its behavior depends on the session mode. With InProc, the value is overridden if the app pool recycles; for persistence across restarts or load-balanced nodes, use StateServer or SQLServer mode. In high-security scenarios, combine an appropriate timeout with absolute expiration and explicit re-authentication logic via a base controller or HTTP module. Always monitor usage patterns and adjust the timeout to balance resource consumption and user experience, especially if deploying to Azure App Service where idle timeouts and scale-out can impact session persistence.

Thanks and regards,

Taz
