Functions

func New

func New(opts ...Options) express.Handler

New returns middleware that appends each configured field to the response's Vary header. Duplicate entries already present on the header are skipped so the header stays tidy.

Types

type Options

type Options struct {
	// Fields is the list of header names to append to the Vary header.
	Fields []string
}

Options configures the vary middleware.
