title: Spring Boot HTTP2 Server Push
body: <p>Found the nice example from Brian Clozel about HTTP/2 and Spring Boot, especially with Server Push: <a href="https://github.com/bclozel/http2-experiments" rel="noreferrer">https://github.com/bclozel/http2-experiments</a>.
  There is an <code>index.html</code> which has some image resources. However, those image are pushed to the server, but I have no idea where exactly this push is initiated from. I don't see any push filters or any other indicators which could lead to push the resources inside the <code>index.html</code>. Any ideas?</p>
