Does any have examples of using x-correlation-ID in an iRule?

For security audit and troubleshooting reasons, a unique correlation ID can be passed from the front door (F5) to the application ( and passed forward from there ).

See these prior posts for additional, related information. https://devcentral.f5.com/questions/correlation-id-generated-by-an-irule

The post below is focused on unique visitors but in today’s world we generally need to correlate by request https://devcentral.f5.com/questions/how-to-generate-visitor-id-uuid
