Request id

A good thing to know is that every request passed through this interceptor, has an id. This does not mean that is a unique id. The id is used in a number of ways, but the most important is to bind a request to its cache.

The id generation is good enough to generate the same id for theoretically sames requests. The example of this is a request with { baseUrl: 'https://a.com/', url: '/b' } results to the same id with { url: 'https://a.com/b/' }.

Also, a custom id can be used to treat two requests as the same.

axios.get('...', {
  id: 'my-custom-id',
  cache: {
    // other properties...
  }
});

The default id generation can clarify this idea.
