paths for which to check bot's permission, defaults to "/". Please, note that path to a folder should end with a trailing slash ("/").
Domain for which paths should be checked. Defaults to "auto". If set to "auto" function will try to guess the domain by parsing the paths argument. Note however, that these are educated guesses which might utterly fail. To be on the safe side, provide appropriate domains manually.
name of the bot, defaults to "*"
HTTP user-agent string to be used to retrieve robots.txt file from domain
at the moment only kept for backward compatibility reasons - do not use parameter anymore --> will let the function simply use the default
if TRUE instead of using possible cached results the function will re-download the robotstxt file HTTP response status 404. If this happens,
analog to CURL option https://curl.haxx.se/libcurl/c/CURLOPT_SSL_VERIFYPEER.html -- and might help with robots.txt file retrieval in some cases
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.
either NULL -- the default -- or a list of character vectors with one vector per path to check
make function print out more information
handler function that handles request according to the event handlers specified
function that executes HTTP request
request state handler for any 5xx status
request state handler for any 4xx HTTP status that is not 404
request state handler for HTTP status 404
request state handler for any 3xx HTTP status
request state handler for any 3xx HTTP status where domain did change as well
request state handler for content type other than 'text/plain'
request state handler for content that seems to be something else than a robots.txt file (usually a JSON, XML or HTML)
