Real-Time Updating for Multiple Users Using Long-Polling

Question asked by sjerrysss on Sep 17, 2019

I'm using IIS Express as server for my application.

 

I've created a map that allows users to input lat and long to draw Symbols on map. Now my goal is to allow users to see other users' Symbols in real-time as they add it to the map without refreshing the page. For instance, UserA draws a Symbol on [121, 24]; UserB must see the Symbol drawn by UserA in real-time.

 

My issue is that I have little knowledge of client-server, so it's nearly impossible for me to sort the code out, not to mention using WebSockets. But I still have to finish the project, so wanna know anyone knows how to real-time update using long-polling?
