StreamingHttpResponse with yield on localhost vs server

Using Django Deployment
1

I have in my views.py :

from django.shortcuts import render
from django.http import StreamingHttpResponse
import time

def home(request):
    return render(request, 'home.html', {})

def automate_run(request):    
    response = StreamingHttpResponse(automate_foo(), content_type="application/json")
    response['Cache-Control'] = 'no-cache'
    return response

def automate_foo():    
    for i in range(1, 11):
        status = "Step %d" % i
        percentage = i * 10
        json_string = f'[{{"status": "{status}","percentage": "{percentage}"}}]'
        print(json_string)
        yield json_string
        time.sleep(.5)

This works smoothly on my localhost on Windows 11 with apache2 and macOS Ventura with apache2 showing 1,2,3 … 10 one after the other every half second. But on my server at https://yield.anjanesh.com it outputs the JSON in console after 5 seconds in one go and not streaming to the HTML page.

I checked this on 2 servers, one on Azure with nginx where I set proxy_buffering off but still no streaming.

How is this working on locahost and not on my server(s) ?

Hi.

Based on this SO thread, you may consider adding following header to your response when using Nginx:

response['X-Accel-Buffering'] = 'no'
