This subject has been asked a couple of time, but I still don't understand something:
When I read answers about
No 'Access-Control-Allow-Origin' header
issue, it says a setting should be set on the requested server in order to allow cross domain:
add_header 'Access-Control-Allow-Origin' '*';.
But, please tell me why when asking from postman (which is a client), It's working like a charm and I have a response from the requested server?
