here are some link explaining and showing how it's done via IE:
with twebbrowser: http://dn.codegear.com/article/26531
with url api: http://www.experts-exchange.com/Programming/Languages/Pascal/Delphi/Q_21249531.html
and uploading files too: http://delphi.about.com/od/delphitips2007/qt/httppost_delphi.htm

and using indy, you can find some on my site. they are specifically persistent login examples in various sites. the idea with indy is that you need to manage cookies by yourself, somthing IE does automatically for you ;) but if you don't need the overhead of IE, then indy can be a solution:

yes the link
 http://dn.codegear.com/article/26531
was what i am looking for
------
procedure TForm1.Button5Click(Sender: TObject);
var
  EncodedDataString: string;
  PostData: OleVariant;
  Headers: OleVariant;
  I: Integer;
begin
  // First, create a URL encoded string of the data
  EncodedDataString := 'login=login'  +   '&pass=sss'   ;

   // The PostData OleVariant needs to be an array of bytes as large
  // as the string (minus the NULL terminator)
  PostData := VarArrayCreate([0, Length(EncodedDataString) - 1], varByte);
  // Now, move the Ordinal value of the character into the PostData array
  for I := 1 to Length(EncodedDataString) do
    PostData[I-1] := Ord(EncodedDataString[I]);
  Headers := 'Content-Type: application/x-www-form-urlencoded' + #10#13;
  // Finally, we just Navigate to the URL. Note that you may have to modify
  // the path to your ASP page's location.
  WebBrowser1.Navigate('http://xxxxx.com/testme.php', 1,EmptyParam, PostData, Headers);
end;
