Gorilla Session not setting cookie

here is the code for my go server, I have no idea why my gorilla session isn't working. it seems like everything works up to session.save(r, w). I already checked my cookies using the chrome dev tools and no matter what I do I can't get a cookie to appear. I know that my authentication is bad already I just need help with getting sessions working which is my goal. I don't know why this function isn't working can anybody help?

package main

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

    "github.com/gorilla/context"
    "github.com/gorilla/sessions"
)

var store = sessions.NewCookieStore([]byte("super-secret"))

func loginAuthHandler(w http.ResponseWriter, r *http.Request) {
    r.ParseForm()
    username := r.FormValue("username")
    password := r.FormValue("password")
    fmt.Println("username:", username, "password:", password)

    if password == "welcome" && username == "guest" {
        fmt.Fprintf(w, "You logged in Succesfully!")

        session, _ := store.Get(r, "session")
        session.Values["authenticated"] = true
        session.Save(r, w)

        fmt.Println("session started!")
        fmt.Println(session)
    } else {
        fmt.Fprintf(w, "Wrong Login!")
    }
}

func secret(w http.ResponseWriter, r *http.Request) {
    session, _ := store.Get(r, "session")

    fmt.Println(session.Values["authenticated"])

    if auth, ok := session.Values["authenticated"].(bool); !ok || !auth {
        http.Error(w, "Forbidden", http.StatusForbidden)
        return
    }

    fmt.Fprintf(w, "The cake is a lie!")

}

func main() {
    store.Options = &sessions.Options{
        Domain:   "localhost",
        Path:     "/",
        MaxAge:   3600 * 8,
        HttpOnly: true,
    }

    http.HandleFunc("/secret", secret)
    http.HandleFunc("/loginauth", loginAuthHandler)
    http.Handle("/", http.FileServer(http.Dir("public")))
    log.Fatal(http.ListenAndServe(":3002", context.ClearHandler(http.DefaultServeMux)))
}
