As part of the certificate creation process, the Let's Encrypt needs to validate the domain name you have provided using a challenge request.
The Edgenexus SSL Certificate Manager does this by using flightPATH, meaning that you can create SSL certificates as needed without doing this on the actual servers.
When you click on the Issue Certificate button, the EdgeADC creates a flightPATH rule that intercepts the challenge request from the certificate-issuing authority, Let's Encrypt, or any supported ACME system.
The flightPATH rule then initiates a request redirect to the Edgenexus SSL Certificate Manager rather than the real server for which it is intended. The Edgenexus SSL Certificate Manager then acknowledges the challenge request and validates it for certificate issuance.
Everything is done automatically from within the EdgeADC itself, without any intervention required from the administrator.
