How can chunked requests be implemented in the Iris plugin for Caddy?

[shivabohemian]

Hello,

After developing an Iris plugin for Caddy, I routed requests to Iris once the iris.Application was built, with code that looks something like this:

type IrisPlugin struct {
	App      *iris.Application
}

func (p *IrisPlugin) CaddyModule() caddy.ModuleInfo {
	return caddy.ModuleInfo{
		ID:  "http.handlers.iris_plugin",
		New: func() caddy.Module { return new(IrisPlugin) },
	}
}

func (p *IrisPlugin) Provision(ctx caddy.Context) error {
        p.App = iris.New()
        // some routers
	addRouter(p.App)
	p.App.Build()
}

func (p *IrisPlugin) ServeHTTP(w http.ResponseWriter, r *http.Request, next caddyhttp.Handler) error {
	p.App.ServeHTTP(w, r)
	return next.ServeHTTP(w, r)
}

// other codes...

This allows Iris to handle requests. However, the issue arises when an endpoint in Iris returns a chunked response, which doesn't seem to take effect. How should I implement the ServeHTTP method for the Caddy plugin to address this?
