*Edge for Private Cloud v4.18.01*

By default, a session in the Edge UI expires one day after login. That means Edge UI users
have to log in again after the session expires.

You can configure the session timeout be setting the conf_application_session.maxage property in
the /opt/apigee/customer/application/ui.properties
file.

To set this property:

1. Open the ui.properties file in an editor. If the file does not exist, create it::  
   \> vi /opt/apigee/customer/application/ui.properties
2. Set conf_application_session.maxage as a time value and time unit. Time units can be:
   - m, minute, minutes
   - h, hour, hours
   - d, day, days  

     For example, set conf_application_session.maxage as: conf_application_session.maxage="2d"
3. Save your changes.
4. Restart the Edge UI:  
   \> /opt/apigee/apigee-service/bin/apigee-service edge-ui restart
