For the rest, here is how it works. Firstly to run it do the following: ruby search-engine-main.rb -c web -d 3 -p 100 -f 'urls.txt'. where: -c (is either 'web' or 'domain') -d (is the depth of the crawl, it will only look at links this many levels below the initial urls) -p (is the page limit, will not crawl more than this many pages ...
Windows 2000 automatically sets a configuration option to use HTTP 1.1 for connecting to web sites. Many, many web sites do not use that version but continue to use HTTP 1.0, so the automatic setting may prevent connections. This is the reason why Xenu would not run for me. When I disabled that setting, Xenu performed properly.
A typical crawler works in the following steps: Parse the root web page ("mit.edu"), and get all links from this page. To access each URL and parse HTML page, I will use JSoup which is a convenient web page parser written in Java. Using the URLs that retrieved from step 1, and parse those URLs
The last idea I have is to implement a crawler algorithm similar to the ones used by Google's own web spiders. My above crawler algorithms only consider the main 'home' addresses, consisting of the 16 characters and the .onion, even though most sites have many pages (fh5kdigeivkfjgk4.onion would be indexed, fh5kdigeivkfjgk4.onion/home would not).

Web Robots (also known as bots, web spiders, web crawlers, Ants) are programs that traverses the World Wide Web in an automated manner. Search engines (like Google, Yahoo etc.) use web crawlers to index the web pages to provide up to date data.
Mocking: This is the process of substituting the response from 3rd dependencies so that they are not actually called during the test. This is the approach used here. Instead of using the crawler.js module to call the url, I used Jest to Mock the module and return a response. This makes the test faster and more predictable.
Web crawler is a computer program that browses the World Wide Web in a methodical, automated manner. Features of a crawler Must provide: Robustness: spider traps Infinitely deep directory structures: pages filled a large number of characters. URL filter: test whether A Web page with the same content has already been seen at another URL.
You are running crawlers locally? Or is this for a site that will be published on the Web at some point, and you want to test the robots.txt now (i.e., if it would work as intended as soon as the site is online)? -
