Sessions

Everything here works based on sessions. Here's how it works:

1. User connects
2. User either sends auth token or session ID/token pair.

• If auth token:
  1. Session server contacts cahcreator.com to verify auth token
• If session ID/token:
  1. Session server verifies locally if session with ID exists and that it has the matching token.

3. Once authenticated:

• If auth token:
  1. Session server contacts cahcreator.com again, this time verifying if the user has access to the deck.
  2. If has_access is true (or user is admin), create a session and send the deck information to the user.
• If session ID/token:
  1. Send deck information over to user (authentication is implied).
  2. Add them to session.

4. On disconnect:

• If user is session creator:
  1. Send session:end message to all users in session.
  2. Nullify session.
  3. Clean up.
• If user is not session creator:
  1. Remove user from session.
  2. Do nothing.
