Setting and getting a cookie in middle ware

Question

My application relies on cookies and I want to test my user's browser to see if it accepts cookies. I use one middle ware to set a test cookie and another one to read the cookie. It looks like the cookie does not get set to begin with so there is nothing to read.

package main

import (
    "fmt"
    "log"
    "net/http"
    "time"

    "github.com/gorilla/mux"
)

var testCookieName = "testCookieName"
var testCookieValue = "12345"

func setTestCookie(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        //testCookieName = "testCookieName" //genUUID()
        //testCookieValue = "12345" //genUUID()
        cookie := http.Cookie{}
        cookie.Name = testCookieName
        cookie.Value = testCookieValue
        cookie.MaxAge = time.Now().Minute() * 60
        //cookie.Domain = config.Domain
        cookie.Path = "/"
        cookie.Secure = false   //true
        cookie.HttpOnly = false //true
        next.ServeHTTP(w, r)
    })
}

func getTestCookie(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        tokenCookie, err := r.Cookie(testCookieName)
        if err != nil {
            fmt.Println(err.Error())
            http.Redirect(w, r, "/cookiefail", http.StatusTemporaryRedirect)
            return
        }

        fmt.Println(testCookieName)
        fmt.Println(testCookieValue)
        fmt.Println(tokenCookie.Value)

        if testCookieValue != tokenCookie.Value {
            http.Redirect(w, r, "/cookiefail", http.StatusTemporaryRedirect)
            return
        }

        next.ServeHTTP(w, r)
    })
}

func main() {
    router := mux.NewRouter()
    router.Use(setTestCookie)
    router.Use(getTestCookie)

    router.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Hello, world!"))
    })

    s := &http.Server{
        Addr:    ":7088",
        Handler: router,
    }

    log.Fatal(s.ListenAndServe())
}

Any idea to what is wrong with my code or suggestion for another method?
