Push solutions like long-polling and websockets are a separate concern. It's perfectly possible to use those technologies in a web app that's primarily still multi-page, such as a stock ticker on an otherwise static page. I would draw the distinction in navigation. Are links primarily triggering built-in browser navigation (MPA) or are they handled by long-running in-browser code, backed by asynchronous requests for additional server data (SPA)?
