Error provides you a generic and extensible framework to handle errors, but it won't do exactly what you're looking for.

You basically need a method of retrying, which can be handled as BrowserUk states, or, based upon your code - can be something like:

  # CODE NOT TESTED 
  # for display purposes only 
  # void in Utah

  my $rc = undef;
  my $i = 0;
  do {
    $rc = go_to_web_page();
  } 
  while ( !$rc && $i++ < 3 );

or, perhaps, using Error

  # CODE NOT TESTED 
  # for display purposes only 
  # void in Utah

  my $i = 0;

  GET_PAGE:
  while ( $i < 3 ) {
    try {
      go_to_web_page();
      # the above has to throw some kind of error 
      # for this to work
      last GET_PAGE;
    } 
    catch Error with {
      $i++;
    };
  }

I'm sure there's a cleaner way to do that, but it's just an example off the top of my head (proof of concept).
