Delphi-PRAXiS - Prism POST funktioniert nicht.

Hallo

Ich habe mich mal an einem Post in einem Forum über einen POST versucht. kann mir jemand sagen, warum der POST nicht ankommt.

Delphi-Quellcode:

			  
  parama:= TIdMultiPartFormDataStream.Create;

  parama.AddFormField('_charset_' ,'utf-8');

  parama.AddFormField('uid',userid);

  parama.AddFormField('text','Hallo Welt');

  parama.AddFormField('submit','Senden');

  parama.AddFormField('bestaetigung','0');

  host:='http://www.planetromeo.com/'+session+'/msg/?id='+messageid;

  memo2.Lines.Add('verwendete URL = '+host);

  memo1.Lines.Add(IdHTTP1.Post(host,parama));

Code:

			<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<title>huhn2010 | Message</title>

<link href="/css/css.php/11.2" type="text/css" rel="stylesheet" />
