I've read the documentation and i have a doubt with createEngine and seekEngine.

I understand that createEngine works in the same way that seekEngine if already exists a master push-page with SHARE_SESSION especified in the creation of the engine , isn't it?

I explain it:
In every page I have, i use createEngine with SHARE_SESSION flag.

- the first page i load create the engine instance --> MASTER PUSH-PAGE
- in another window, i load another page that try to create the engine again , but doesn`t do it because the engine already exists --> this page use the current Engine instance --> PUSH-PAGE

In the second page, should I use seekEngine instead of createEngine?
