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The cache is cleared after a delay in order to avoid returning out-of-date data.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).
Changing the option has no impact on requests that were already memoised.
The proxy settings are set through the rgho.http_proxy option. Proxy is passed as a character strings of the form "http://username:password@url:port".
Failed requests are retried a maximum of options("rgho.retry") (by default 5 times).
