Handler relays an agent configuration from a trusted HTTP endpoint.

Serve fetches and returns the configuration. It writes a generic error to the client and returns the detailed cause for logging.

func (h *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP fetches and returns the configuration.

type Option func(*Handler)

Option configures a Handler.

func WithClient(client *http.Client) Option

func WithMaxBytes(n int64) Option

WithMaxBytes sets the maximum accepted configuration size.

func WithTimeout(timeout time.Duration) Option

WithTimeout sets the end-to-end upstream request timeout.

type Source func(*http.Request) (*url.URL, error)
