The web server configuration parameter authenticated-user-header activates header authentication by specifying the name of the HTTP header field that will be used to pass the username to TiddlyWiki.

For example, if the authenticated-user-header is set to X-Authenticated-User, then the HTTP request must include a header field X-Authenticated-User with a value that is the username:

X-Authenticated-User: JeremyRuston

New in: 5.3.0 Value of this header field should be URI-encoded before transit on the client (using encodeURIComponent JS function or encodeuricomponent Operator), and will be URI-decoded by the server.
