Robots_txt takes the URL of a page and retrieves the robots.txt file of the same site. The robots.txt is parsed and the rules defined in it are looked up, in order to determine if crawling a page is allowed.
Robots_txt also stores the time when a page is crawled to check whether next time another page of the same site is being crawled it is honoring the intended crawl delay and request rate limits.
