module HTTP::Handler

What serves requests: a Router, a procedure (HTTP.handler) or a class or data of one's own. Handlers are Shareable, since every connection's task calls them: state shared between requests lives in an Atom or a Channel. Middleware is a handler holding the next.

data DocLogged_HTTP(inner: HTTP::Handler)
  include HTTP::Handler

  def call(req: HTTP::Request) -> HTTP::Response
    inner.call(req).header("x-served-by", "quarz")
  end
end

app = DocLogged_HTTP.new(HTTP.handler { |req| HTTP::Response.text(req.path) })
app.call(HTTP::Request.get("/a")).headers["x-served-by"]   # => "quarz"
