On Sandbox, there is a 3 minute session timeout value configured. When the session times out and I click reload, the button does not take me back to the new login.

Browser: Any
URL: https://cfasbx.cfainformdev.net/MMS_stores_dlpscontainer.htm

Steps
1. Navigate to the above URL
2. Enter the DLPS credentials for store 00440
Observe: DLPS data displays successfully for the dlpscontainer.htm
3. Allow 3 minutes to pass
4. click Reload button
Results: The browser attempts to redirect to the MMS login and generates a Feature Unavailable
Expected: Browser should direct back to the new login
