Ajax allows you to access the server, get a response, and render without refreshing the page. Whether it is possible to send data from the server to the page without a request from ajax. For example, the client sent a file, the site displays information about the processing stage , and then about readiness. How to implement this in django? Sorry if I phrased the question badly .
Having said that, there is a Django package called Channels that can help integrate Django with a persistent connection environment.
