Why increasing of session timeout maybe not works
In some cases, when you increase session timeout, then run web application, session will still expire. There could be few possible reasons for this.

Notice that session timeout should be less than Application pool idle timeout, so if you increase session timeout, you have to increase application idle timeout too. Otherwise, application will get recycled. If application is recycled, sessions will expire automatically.
