TWebURLValidator

TWebURLValidator is a non-visual component that allows to perform a check whether an URL exists and works or not. Set the URL to test via TWebURLValidator.URL and call the Validate method. This will trigger the OnValidated event where the IsValid parameter will return whether the URL is valid or not.

Example:

procedure TForm1.WebFormCreate(Sender: TObject);
begin
  WebURLValidator1.URL := 'http://myurltotest.com';
  WebURLValidator1.Validate;
end;

procedure TForm1.WebURLValidator1Validated(Sender: TObject; IsValid: Boolean);
begin
  if IsValid then
    ShowMessage('The URL ' + WebURLValidator1.URL + ' works!');
end;
