Like every web app, wayahead uses a session to store when you log in and when you were last active. Sessions can't be kept alive forever, so every now and again a while you will need to log in again. When your session expires, you will be logged out automatically and you might see a code=39 or code=40 in the url of the long page.
This article helps you understand the different lifespans of a session.
Once you log in to wayahead, your session will remain active as you refresh pages or navigate around between reports.
By default, wayahead will log you out automatically:
If you have been inactive for a day (24 hours)
If it has been more than 5 days since your last login (and your account was idle for over 1 hour)
When you check "Remember Me" during login, your session will be kept alive for 10 days.
