6/// `Server` header, defined in [RFC7231](https://datatracker.ietf.org/doc/html/rfc7231#section-7.4.2)
7///
8/// The `Server` header field contains information about the software
9/// used by the origin server to handle the request, which is often used
10/// by clients to help identify the scope of reported interoperability
11/// problems, to work around or tailor requests to avoid particular
12/// server limitations, and for analytics regarding server or operating
13/// system use.  An origin server MAY generate a Server field in its
14/// responses.
