no effect of cache-control no-store seen in nginx in chrome dev tools, why?

I first downloaded two images.

Put them into /usr/share/nginx/html/img directory.

One was named pic-1.jpg, another was named pic-2.jpg.

Remember, I’ve not added any cache control headers till date.

Now, I went to my-ip-address:80/img/pic-1.jpg. Then I clicked reload a couple of times, so that I can check dev tools and find cache stored there.

But to my surprise, I didn’t find anything stored there.

# curl -I 192.168.1.76:80/img/pic1.jpg
HTTP/1.1 200 OK
Server: nginx/1.20.1

This was the output being returned via terminal curl.

I could not open about:cache in google chrome at all, so had to look into chrome dev tools.
