How to make an asynchronous request in vue-resource?

Question

Vue.js

Hey! With 2 ajax requests through vue-resource, 401 is returned when the token expires.

let allowRefresh = true
Vue.http.interceptors.push((request, next) => {
  next((response) => {
    if (allowRefresh && response.status === 401) {
      allowRefresh = false
      store.commit('SET_AUTH_REFRESHING')
      return user.refresh(request).then(result => {
        return Vue.http(request).then(data => {
          return data
        })
      }, () => {
        user.logout()
      })
    }
  })
})

But since the requests go synchronously, the first one after 401 updates the token and continues its request. But the second is simply lost.

So, is it possible to somehow stop subsequent requests after the first one until it completes and installs a new token?
