Scenario:  You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page.
