## What it is
A PHP demo showing how users can be tracked via HTTP ETag headers instead of cookies or localStorage. It serves as an educational proof-of-concept of cookieless tracking techniques.

## Use cases
- demonstrate etag-based tracking
- learn how cookieless tracking works
- test browser privacy against etag tracking
- educate users about web tracking without cookies
- research privacy implications of etag caching

## When to choose
- you need a working demo of etag tracking for education or research
- you want to test privacy tools or browser extensions against etag tracking

## When to avoid
- you need production-ready tracking or analytics software
- you want actively developed privacy tooling rather than a proof-of-concept

## Facets
- artifact type: application
- maturity: maintenance
- function: security, privacy, http-server
- domain: privacy, web-development, security
- platform: php, self-hosted
- tags: tracking, etags, browser-fingerprinting, demo, privacy-research, web-server
