i have a cgi application  which contains submit button. after hitting the submit button, my application saves customers email addres in flat file
if some nasty user keeps on hitting the submit button, my application keeps on saving the information on file. this is redendant.

also i have a counter  using File::CounterFile

if the same url user keeps hitting refresh button, i don't want to increase the counter as it comes from same ip.
how do i prevent this.

use one file per email address, then hitting again or using refresh writes the same file
I'd use the email address itself as filename (after proper sanitation)

> ..  i don't want to increase the counte
my $file = $ENV{'REMOTE_ADDR'};
if ( ! -e $file ) {
  my $c = CounterFile->new("$CONFIG::DATA/your-counter");
  open( F,">$file") && close F;
}
