Hi Monks!

I have a program that get inputs from a form to insert data into two database tables, the problem is when I am done with the inserts the last thing that this sub routine does is to call another sub routine to display the results to the user so they can print them. My problem is if they refresh the browser I am getting the whole thing inserted into the database again. What would be the best way to prevent such thing to happen?
I was thing about setting up a cookie at the begging of my code and read the cookie at the beginning of my insert sub routine, and if the cookies exist redirect them, any thoughts? 

sub insert
{

my %cookies = fetch CGI::Cookie;
# retrieve the user_id cookie
my $section = $cookies{"id"};
if($section){
# If the cookies has been set send them back somewhere.
&display;
}

get all the values from form .......
do the inserts

done with insert...

#call display sub to user

&display;

} # end sub insert
