Types

type Header

type Header struct {
	Name  string
	Value string
}

Header represents a single HTTP header, simply a name and value.

type Headers

type Headers struct {
	Next  middleware.Handler
	Rules []Rule
}

Headers is middleware that adds headers to the responses for requests matching a certain path.

func (Headers) ServeHTTP

func (h Headers) ServeHTTP(w http.ResponseWriter, r *http.Request) (int, error)

ServeHTTP implements the middleware.Handler interface and serves requests, setting headers on the response according to the configured rules.

type Rule

type Rule struct {
	Path    string
	Headers []Header
}

Rule groups a slice of HTTP headers by a URL pattern. TODO: use http.Header type instead?
