Is it possible to track where the server makes http requests?

Answer 1

If he does them from a server, say PHP curl, then it is impossible, except to guess by external signs.
If they are made by JavaScript or Flash, then they are not on the site, but in your browser, this is an untrusted environment, that is, nothing can be fully "hidden", requests are tracked using sniffer, for HTTP, Fiddler and the Network tab in Chrome are the most convenient sniffers DevTools, in addition, you can debug not only requests, but also control the JavaScript code itself, again in Chrome DevTools.
