The exact urls and content types to be strapped can be set using logical workflows and regex/wildcard rules. Screen-scraping is made easier with identity control, automatically managing threads, rate limits, urls, duplicates, retries, proxies, headers and cookies into a an army of virtual browser which can mimic human behavior and even client buttons, fill in forms or log in behind security walls.
