# Proactively Invalidate Sessions After Defined Durations

The **glide.active.session.timeout.invalidate.session** property controls whether a timeout session is proactively invalidated before the Tomcat server.

When **glide.active.session.timeout.invalidate.session** isn't set to true, there’s a small interval of time where a timed-out session isn’t invalidated proactively before the Tomcat container invalidates the session. The duration of this time interval is dependent on additional properties representing differing use cases.

|Property|Description|
|--------|-----------|
|glide.ui.active.session.life\_span|The value of this property defines the time, in minutes, before a UI session is invalidated.|
|glide.guest.active.session.life\_span|The value of this property defines the time, in minutes, before a guest session is invalidated.|
|glide.integrations.active.session.life\_span|The value of this property defines the time, in minutes, before an integrations session is invalidated.|

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