Types ¶
type HTTPHandler ¶
type HTTPHandler struct {
// required, the URL that requests will be forwarding to
To *url.URL
// optional, preserve the host in outbound requests
PreserveHost bool
// optional, but in fact required, injecting fingerprint headers to outbound requests
HeaderInjectors []HeaderInjector
// optional, if IsProbeRequest returns true, handler will respond with
// a HTTP 200 OK instead of forwarding requests, useful for kubernetes
// liveness/readiness probes. defaults to nil, which disables this behavior
IsProbeRequest func(*http.Request) bool
// contains filtered or unexported fields
}
func NewHTTPHandler ¶
func NewHTTPHandler(to *url.URL, reverseProxy *httputil.ReverseProxy, headerInjectors []HeaderInjector) *HTTPHandler
NewHTTPHandler creates an HTTP handler, changes `reverseProxy.Rewrite` to support request header injection, then assigns `reverseProxy` to the handler which proxies requests to backend
func (*HTTPHandler) ServeHTTP ¶
func (f *HTTPHandler) ServeHTTP(w http.ResponseWriter, req *http.Request)
