      <br>
      getsockopt(3, SOL_SOCKET, SO_ERROR, [0], [4]) = 0
      <br>
      fcntl(3, F_GETFL)                       = 0x802 (flags

      = 112
      <br>
      recvfrom(3,
      <br>
      <br>
      If I do the same with 'wget' it also hangs but in the end gets
      through..
      <br>
      <br>
      But if you add some headers, you get a proper error response.
      <br>
      <br>
      There is little I can do about that. I can only surmise Indy &
      wget send different
      <br>
      headers (E.G.user-agent) and the server reacts differently on
      that.
