Wie komme ich an den Html-Quellcode eines DefaultHttpClient

//Loginfelder die übermittelt werden
List <NameValuePair> nvps = new ArrayList <NameValuePair>();
    	nvps.add(new BasicNameValuePair("credential_0", this.teleNr));
    	nvps.add(new BasicNameValuePair("credential_1", this.passWd));
    	nvps.add(new BasicNameValuePair("destination", "this.desti"));


		//Versuch mit Post
    	HttpPost httpost = new HttpPost(this.baseURL);
    	//Nummer und Passwort mit request mitsenden
		httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
 	
		//Senden und Antwort erhalten 
    	HttpResponse response = httpClient.execute(httpost);
		//Die Nachricht der Antwort 
    	HttpEntity entity = response.getEntity();
    	if (entity != null) {
        	//flush
			entity.consumeContent();
    	}
    	//Cookie speichern
    	List<Cookie> cookies = httpClient.getCookieStore().getCookies();
    	if (cookies.isEmpty()) {
    		Log.e(LOG_TAG, "None");
    		return false;
    	}

ByteArrayOutputStream content = new ByteArrayOutputStream();


            	// Read response into a buffered stream
            	int readBytes = 0;
            	byte[] sBuffer = new byte[512];
            	while ((readBytes = data.read(sBuffer)) != -1) {
                	content.write(sBuffer, 0, readBytes);
            	}
         	// Return result from buffered stream
            	String dataAsString = new String(content.toByteArray());
