Arguments

domain	domain from which to download robots.txt file
warn	warn about being unable to download domain/robots.txt because of
force	if TRUE instead of using possible cached results the function will re-download the robotstxt file HTTP response status 404. If this happens,
user_agent	HTTP user-agent string to be used to retrieve robots.txt file from domain
ssl_verifypeer	either 1 (default) or 0, if 0 it disables SSL peer verification, which might help with robots.txt file retrieval
use_futures	Should future::future_lapply be used for possible parallel/async retrieval or not. Note: check out help pages and vignettes of package future on how to set up plans for future execution because the robotstxt package does not do it on its own.
verbose	make function print out more information
rt_request_handler	handler function that handles request according to the event handlers specified
rt_robotstxt_http_getter	function that executes HTTP request
on_server_error	request state handler for any 5xx status
on_client_error	request state handler for any 4xx HTTP status that is not 404
on_not_found	request state handler for HTTP status 404
on_redirect	request state handler for any 3xx HTTP status
on_domain_change	request state handler for any 3xx HTTP status where domain did change as well
on_file_type_mismatch	request state handler for content type other than 'text/plain'
on_suspect_content	request state handler for content that seems to be something else than a robots.txt file (usually a JSON, XML or HTML)
