How to use offline validation using TTL and cached response


Some of my customers do not have instant internet access. How to use offline validation in this scenario?


Every NetLicensing validation response contains an attribute with the TTL (Time-To-Live) value. Successful validation response can be cached with the expiry time set to this interval and used to validate product without sending online validation request.

TTL Interval can be defined in the Settings form and be in the range from 1 minute to several days.

Caching functionality need to be realised by means of the specific product implementation and technology stack.
