var _ caddyhttp.MiddlewareHandler = (*RequestBody)(nil)

RequestBody is a middleware for manipulating the request body.

type RequestBody struct {
	// The maximum number of bytes to allow reading from the body by a later handler.
	// If more bytes are read, an error with HTTP status 413 is returned.
	MaxSize	int64	`json:"max_size,omitempty"`

	// EXPERIMENTAL. Subject to change/removal.
	ReadTimeout	time.Duration	`json:"read_timeout,omitempty"`

	// EXPERIMENTAL. Subject to change/removal.
	WriteTimeout	time.Duration	`json:"write_timeout,omitempty"`

	logger	*zap.Logger
}

errorWrapper wraps errors that are returned from Read() so that they can be associated with a proper status code.

type errorWrapper struct {
	io.ReadCloser
}

func (rb *RequestBody) Provision(ctx caddy.Context) error {
	rb.logger = ctx.Logger()
	return nil
}

CaddyModule returns the Caddy module information.

func (RequestBody) CaddyModule() caddy.ModuleInfo {
	return caddy.ModuleInfo{
		ID:	"http.handlers.request_body",
		New:	func() caddy.Module { return new(RequestBody) },
	}
}

		r.Body = errorWrapper{http.MaxBytesReader(w, r.Body, rb.MaxSize)}
	}
	if rb.ReadTimeout > 0 || rb.WriteTimeout > 0 {
