if (success <> 1) then
  begin
    Memo1.Lines.Add(http.LastErrorText);

  end;

//  Send the HTTP GET and return the content in a string.
//  (cknotes.com is the Chilkat blog.)

html := http.QuickGetStr('http://www.cknotes.com/');
if (html = NULL ) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

//  This example is about examining the request/response headers, so we're ignoring the html received...

//  Show the HTTP request header:
Memo1.Lines.Add(http.LastHeader);

//  Show the HTTP response header:
Memo1.Lines.Add(http.LastResponseHeader);
