title: Is there any tool to detect/extract which domains will be contacted from an HTML file when this file is loaded on a browser?
body: <p>I have a large number of index.html files generated by crawling a huge number of domains. I am aware that there are tools to parse URLs from text/html files. However, I wonder if there are any tools to parse the domains that will be loaded/contacted from the HTML file if it was opened/rendered in a browser since not all urls in the HTML body will be contacted, but only those needed to render the page.</p>
