ColdFusion (Adobe ColdFusion and the open-source Lucee) is a server-side platform whose pages use the `.cfm` extension. AIWebsiteDetector reports ColdFusion from an `X-Powered-By: ColdFusion` header, the `CFID` and `CFTOKEN` session cookies and relative `.cfm` links. A site that hides these cannot be identified from outside.
