I am currently working in a feature that requires real time communication between browser and server and I am using websocket for the same. But I was a bit surprised when I looked at Google Keep webapp. When I open the network panel I don't see any Websocket or SSE connection being established but if I keep the web app open and make any change on the android app and pull down on the screen on the android app to sync changes, the web app gets refreshed immediately.
Since there is no active Websocket or SSE connection seen in the network panel I am curious if there is any other mechanism to achieve the same without using Websockets?
