Answer 1

I am afraid you will need to create your own custom validator:

class myCustomValidatorUrl extends sfValidatorRegex
{
  const REGEX_URL_FORMAT = '~^
    ((%s)://)?                                 # protocol
    (
      ([a-z0-9-]+\.)+[a-z]{2,6}             # a domain name
        |                                   #  or
      \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}    # a IP address
    )
    (:[0-9]+)?                              # a port (optional)
    (/?|/\S+)                               # a /, nothing or a / with something
  $~ix';

  protected function configure($options = array(), $messages = array())
  {
    parent::configure($options, $messages);

    $this->addOption('protocols', array('http', 'https', 'ftp', 'ftps'));
    $this->setOption('pattern', new sfCallable(array($this, 'generateRegex')));
  }

  public function generateRegex()
  {
    return sprintf(self::REGEX_URL_FORMAT, implode('|', $this->getOption('protocols')));
  }
}

Here ((%s)://)? mean that now protocol is optional. See sfValidatorUrl for an original pattern (REGEX_URL_FORMAT const).

For validating you could use the native PHP function filter_var with the flag FILTER_VALIDATE_URL.
