Redirect back inside middleware

[gribbl]

Hi,

I'm trying to restrict access to /login and /signup pages when a user is already logged in. So, I created a middleware within I checked if the user is logged in. If it's the case I want to redirect him back. Hence, I used response.redirect().back() but it does not work. Actually, I'm always redirected to the home page no matter where I was before the request.

import type { HttpContextContract } from '@ioc:Adonis/Core/HttpContext'

export default class Guest {
  public async handle({ auth, response }: HttpContextContract, next: () => Promise<void>) {
    if (auth.isLoggedIn) {
      return response.redirect().back()
    }
    await next()
  }
}
