  Report a bug

• What is the current behavior?
  When loading a page with preboot installed, http calls are being run twice, once by the server and then again when the client app takes over.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem by creating a github repo.

1. Load a page which makes a http call (in this case using a resolve using the router)
2. The page is correctly loaded but when checking logs, you will notice that the http call has been made twice

• What is the expected behavior?
  The data to be cached instead of the request being called twice

@mogusbi Checkout transfer-state module here:

This is not preboot issue.

Yes, as @marekstabla mentions, you need to cache data between the server and client which requires the transfer state module. Preboot is just focused on the events between the server view and client view (i.e. if someone clicks on something in the server view before the client view finishes bootstrapping).
