You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: get_head.go
    path of file: ./repos/corteza/extra/server-discovery/vendor/github.com/go-chi/chi/v5/middleware
    
    the code of the file until where you have to start completion: package middleware

import (
	"net/http"

	"github.com/go-chi/chi/v5"
)

// GetHead automatically route undefined HEAD requests to GET handlers.
func GetHead(next http.Handler) http.Handler {
	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		if r.Method == "HEAD" {
			rctx := chi.RouteContext(r.Context())
			routePath := rctx.RoutePath
			if routePath == "" {
				if r.URL.RawPath != "" {
					routePath = r.URL.RawPath
				} else {
					routePath = r.URL.Path
				}
			}

			// Temporary routing context to look-ahead before routing the request
			tctx := chi.NewRouteContext()

			// Attempt to find a HEAD handler for the routing path, if not found, traverse
			// the router as through its a GET route, but proceed with the request
			// with the HEAD method.
			
    
func GetHead(next http.Handler) http.Handler {
	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
