The HTTP server will invoke the method <code>ServeHTTP</code>
of that type, with <code>ArgServer</code> as the receiver, which will in turn call
<code>ArgServer</code> (via the invocation <code>f(c, req)</code>
<code>ArgServer</code> (via the invocation <code>f(w, req)</code>
inside <code>HandlerFunc.ServeHTTP</code>).
The arguments will then be displayed.
