config: All configuration options are ignored because the request is handled by the browser, not RCurl.
...: Further named parameters, such as query, path, etc, passed on to modify_url(). Unnamed parameters will be combined with config().
handle: The handle to use with this request. If not supplied, will be retrieved and reused from the handle_pool()
based on the scheme, hostname and port of the url. By default httr
requests to the same scheme/host/port combo. This substantially reduces connection time, and ensures that cookies are maintained over multiple requests to the same host. See handle_pool() for more details.
