Classic ASP is Microsoft's original server-side scripting technology (`.asp` pages on IIS), before ASP.NET. It is still found on older business sites. AIWebsiteDetector reports it from an `X-Powered-By: ASP` header (distinct from `ASP.NET`), the `ASPSESSIONID…` session cookie and relative `.asp` links. A site that hides these cannot be identified from outside.
