CURLHandle-class

This is the basic class used for  performing HTTP requests
  in the RCurl package.
  In R, this is a reference to a C-level data structure
  so we treat it as an opaque data type. However,
  essentially we can think of this as an with
  a set of options that persists across calls, i.e. HTTP requests.
  The numerous options that one can set can be see via
   <code><a href="/link/getCurlOptionsConstants?package=RCurl&version=1.3-1" rd-options="" data-mini-rdoc="RCurl::getCurlOptionsConstants">getCurlOptionsConstants</a></code>.
  The object can keep a connection to a Web server open for a period of time
  across calls.<p></p><p>  This class differs from <code><a href="/link/MultiCURLHandle-class?package=RCurl&version=1.3-1" rd-options="" data-mini-rdoc="RCurl::MultiCURLHandle-class">MultiCURLHandle-class</a></code> as it
  can handle only one request at a time and blocks until the request
  is completed (normally or abnormally).
  The other class can handle asynchronous, multiple connections.</p>

classes

The package allows one to compose general HTTP requests
        and provides convenient functions to fetch URIs, get & post
        forms, etc. and process the results returned by the Web server.
        This provides a great deal of control over the HTTP/FTP/...
        connection and the form of the request while providing a
        higher-level interface than is available just using R socket
        connections.  Additionally, the underlying implementation is
        robust and extensive, supporting FTP/FTPS/TFTP (uploads and
        downloads), SSL/HTTPS, telnet, dict, ldap, and also supports
        cookies, redirects, authentication, etc.
