Method setup_error_transfer

///////////////////////////////////////////////////////////////////// HttpSM::setup_error_transfer() The proxy has generated an error message which it is sending to the client. For some cases, however, such as when the proxy is transparent, returning a proxy-generated error message exposes the proxy, destroying transparency. The HttpBodyFactory code, therefore, does not generate an error message
