This change uses context.WithValue to inject the next handler into the request context via a "nextCall" carrier struct, and pass it on to a standard Go HTTP handler returned by otelhttp.NewHandler. The underlying handler will extract the next handler from the context, call it and pass the returned error to the carrier struct. * use zap.Error() for the error log * remove README.md * update dependencies * clean up the code * change comment * move serveHTTP method from separate file * add syntax to the UnmarshalCaddyfile comment * go import the file * admin: Write proper status on invalid requests (#4569) (fix #4561) * update dependencies Co-authored-by: Dave Henderson <dhenderson@gmail.com> Co-authored-by: Francis Lavoie <lavofr@gmail.com> Co-authored-by: Vibhav Pant <vibhavp@gmail.com> Co-authored-by: Alok Naushad <alokme123@gmail.com> Co-authored-by: Cedric Ziel <cedric@cedric-ziel.com>
