TIdHTTP error details

[Boba TC]

Dear All; when TIdHTTP::Get method throws out an EIdHTTPProtocolException, where do I find details of the error?
For instance:

Code:

TIdHTTP *IdHTTP;
AnsiString strURL="https://....";
//...
try{
  TMemoryStream *m = new TMemoryStream;
  IdHTTP->Get(strURL,m);
  m->SaveToFile("tst.txt");
  delete m;
}catch(EIdHTTPProtocolException &e){
  ShowMessage(e.Message);//shows "HTTP/1.1 400 Bad Request"
}

Thanks in advance. Boba.
