Inactivity
An inactivity sub-element specifies a time-to-live (TTL) value for the cache entry based on the last time that the cache entry was accessed. In Example | -5, the inactivity value, given in seconds, indicates the amount of time to keep the cache entry in the cache after the last cache hit. Note that if a timeout value is less than the inactivity value, then the inactivity value has no meaning and the cache entry is always invalidated before the inactivity time is reached.
Example 3-5 Using inactivity to invalidate
<cache-id>
<component id="storeId" type="parameter">
<required>true</required>
</component>
<component id="DC_userId" type="attribute">
<required>true</required>
</component>
<inactivity>240</inactivity>
<timeout>3600</timeout>
</cache-id>
