# Proactively invalidate sessions after defined durations

The **glide.active.session.timeout.invalidate.session** property controls whether a timed-out session is proactively invalidated before the Tomcat server processes it.

When this property value isn't set to **true**, there’s a brief interval where the application doesn't proactively invalidates the timed-out session before the Tomcat container invalidates it. To enable active session timeout, the user also needs to define at least one of the following session timeout properties:

|Property|Description|
|--------|-----------|
|glide.ui.active.session.life\_span|Defines the timeout period \(in minutes\) for UI sessions.|
|glide.guest.active.session.life\_span|Defines the timeout period \(in minutes\) for guest sessions.|
|glide.integrations.active.session.life\_span|Defines the timeout period \(in minutes\) for integration sessions.|

Ensure that the property **glide.active.session.timeout.invalidate.session** is set to true.
