Request informations can be displayed by setting options("rgho.verbose") to TRUE.
Request results are memoised. The results of requests are cached, and repeating a request with the same parameters will return the cached result without doing a new query.
The cache is cleared after a delay in order to avoid returning out-of-date data. By default this delay is set to options("rgho.memotime") seconds (by default 3600).
rgho tries to fetch MS Windows proxy settings with curl::ie_get_proxy_for_url(). If a list of proxies is returned the request will loop over the list until it succeeds.
Failed requests are retried a maximum of options("rgho.retry") (by default 5 times).
