From header

The HTTP From ~~{{Glossary("~~request ~~header")}}~~header contains an Internet email address for an administrator who controls an automated user agent.

If you are running a robotic user agent (a web crawler, for example), the From header must be sent in requests so you can be contacted if problems occur, such as a bot sending excessive, unwanted, or invalid requests.

~~[!WARNING]~~WARNING: You must not use the From header for access control or authentication.
