вот такая штука ешё -

unit Unit1;

interface

uses
 Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
 Dialogs, wininet, StdCtrls;

type
 TForm1 = class(TForm)
   Memo1: TMemo;
   Button1: TButton;
   procedure Button1Click(Sender: TObject);
   procedure FormCreate(Sender: TObject);
 private
   { Private declarations }
 public
   { Public declarations }
 end;

var
 Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
 hSession, hConnect, hRequest: hInternet;
 Header, httpstring: string;
 Buf: array[0..1023] of Char;
 ReadCount: Cardinal;
 AStream: TMemoryStream;
begin
 Header := "Content-type: application/x-www-form-urlencoded";
 httpstring := "/cgi-bin/forum.pl?id=1076917247&n=4";
 AStream := TMemoryStream.Create;
 hSession := InternetOpen(nil, INTERNET_OPEN_TYPE_PRECONFIG, nil, nil, 0);
 try
   hConnect := InternetConnect(hSession, "delphimaster.ru",
     INTERNET_DEFAULT_HTTP_PORT, nil, nil, INTERNET_SERVICE_HTTP, 0, 0);
   try
     hRequest := HttpOpenRequest(hConnect, "GET",
       pchar(httpstring), "HTTP/1.0", nil, nil,
       INTERNET_FLAG_RELOAD, 0);
     try
       HttpSendRequest(hRequest, Pchar(Header),
         Length(Header), nil, 0);
       while True do
       begin
         if not InternetReadFile(hRequest, @Buf, SizeOf(Buf), ReadCount) then
           Break;

         if ReadCount = 0 then
           Break
         else
           AStream.Write(Buf, ReadCount);
       end;
       AStream.Position := 0;
       memo1.Lines.LoadFromStream(AStream);
     finally
       AStream.Free;
       InternetCloseHandle(hRequest);
     end;
   finally
     InternetCloseHandle(hConnect);
   end;
 finally
   InternetCloseHandle(hSession);
 end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
 memo1.ScrollBars := ssVertical;
 memo1.Clear;
end;

end.
