How to find out the list of external resources used when loading a web page?

Question

Squid

Plz tell me how you can find out the list of external resources used when loading a web page. You need a list of domains other than the website address.
For example, when loading toster.ru, additional content is also loaded from the following domains:
apm.24mon.com
dr.habracdn.net
fonts.googleapis.com
habrastorage.org
googletagservices.com
, etc.
Actually, I'm interested in the way in which you can collect information on ~ 80+ sites. This can be seen manually in the "inspector" of the web page in Google Chrome on the Sources tab. But manually - this is a rather dreary business, because. export of this list in the browser cannot be done automatically.

Answer 1

parse the page and collect tags that have absolute paths. Then remove links from this list (tag a) and here are external resources for you
