is it possible to know from which server the browser url fetching data

when we have multiple servers for a webserver ex: example.com (10 servers).how to track a user getting the response/fetching data form which server in those 10 servers. is it possible to know all requests to track which server is on service.

I've been googling and read many articles , in all those suggesting how it works but still didn't get correct method to analyze.
