The HTTP Sec-Fetch-User request header is included by the client when the HTTP request is initiated by user activation.
The HTTP Sec-Fetch-User request header is sent by the client to help the server identify the source of a HTTP request. If it was originated by the user then this HTTP header will be included with a directive of
?1. There are no other directives.
In this example, the HTTP request for an image, residing on the same origin, was initiated by the user.
Sec-Fetch-User: ?1 Sec-Fetch-Dest: image Sec-Fetch-Mode: navigate Sec-Fetch-Site: same-origin
The HTTP Sec-Fetch-User request header is used to inform the server that the HTTP request originated as a result of the user’s activation.
