title: POCO C++ - NET SSL - how to POST HTTPS request
body: <p>How to correctly do a POST to HTTPS server and embed the login data correctly. Below code does not return any cookies (in Wininet it does). I wonder how POCO HTTP library handles HTTP redirections?</p>
  
  <pre><code>MyApp()
  {
      try
      {
          const Poco::URI uri( "https://localhost.com" );
          const Poco::Net::Context::Ptr context( new Poco::Net::Context( Poco::Net::Context::CLIENT_USE, "", "", "rootcert.pem" ) );
          Poco::Net::HTTPSClientSession session(uri.getHost(), uri.getPort(), context );
          Poco::Net::HTTPRequest req(Poco::Net::HTTPRequest::HTTP_POST, "/login.php" );
          req.setContentType("Content-Type: application/x-www-form-urlencoded\r\n");
          req.setKeepAlive(true);
  
          std::string reqBody("username=???&amp;password=???&amp;action_login=Log+In\r\n\r\n");
          req.setContentLength( reqBody.length() );
  
          //Poco::Net::HTTPBasicCredentials cred("???", "???");
          //cred.authenticate(req);
          session.sendRequest(req) &lt;&lt; reqBody;
          Poco::Net::HTTPResponse res;
          std::istream&amp; rs = session.receiveResponse(res);
          std::string resp;
  
          std::vector&lt;Poco::Net::HTTPCookie&gt; cookies;
          res.getCookies( cookies );
      }
      catch( const Poco::Net::SSLException&amp; e )
      {
          std::cerr &lt;&lt; e.what() &lt;&lt; ": " &lt;&lt; e.message() &lt;&lt; std::endl;
      }
      catch( const std::exception&amp; e )
      {
          std::cerr &lt;&lt; e.what() &lt;&lt; std::endl;;
      }
  
  };
