Unlike the license key string, a remote call to the licensing server is not required to validate the local license key. All information needed to validate the key is included in the key. Because of this, it is usually not a good idea to choose &lt;b&gt;Never Expires&lt;/b&gt; here. Instead, set an expiration term so that periodically the local license key will expire. 

At expiration SPBAS will go remote using the license key string (from above) to fetch a new local license key which will pull in any changes you might have made from the previous period.

By default, SPBAS checks the local key first every time.
