9ping Analytics — sample download ======================================== This is a tiny demo file served by /9ping-sample.txt. When you clicked the "Try a .txt download" button on the demo page, the embedded 9ping tracker auto-detected the file-extension on the anchor's href and fired a custom event: type = event category = file-download action = txt label = /9ping-sample.txt That event landed in the demo0001 report — open https://9ping.dev/app?sid=demo0001 and you'll find it in the Events panel. No server-side magic involved: the SDK watches click events on tags whose href ends with a known download extension (pdf / zip / docx / xlsx / csv / txt / mp3 / mp4 / dmg / apk / ...). — 9ping
