The second do_method does not work in the following testcase:

  void main()
  {
    Protocols.HTTP connection =
      Protocols.HTTP.do_method("GET", "http://www.roxen.com/");
    werror("Connection: %O\n", connection);

    connection =
      Protocols.HTTP.do_method("GET", "http://www.roxen.com/company/",
  			       0, 0, connection);
    werror("Connection: %O\n", connection);
  }

Output:
