CGI - unreloadable page?

[Roman Khutkyy]

Hi all.
There is a problem (i hope so). When i submit the form first time, the
script put fields data into database. But when on next page i make "Reload"
this process repeats again, and the same record are being placed. How to
disallow this. I mean, how to make the new page withot any parameter in
address string?

Note that this is not a Perl language question, so you are not at the
right place.

Anyway, if the parameters appear in the address bar, the form was
submitted using the GET method. To avoid that, you can use the POST
method.

That does not prevent the data to be resubmitted if you make a
"Reload", but I believe that browsers typically ask before
resubmitting form data.

POST the data to a scripts that does whatever processing you require and
then redirect the user to another page. If they then reload that page
there wont be any parameters to re-send and it will be a different page
anyway.

use CGI;
print $query->redirect($url);

use CGI;
print $query->redirect($url);

Sorry, should have been;

use CGI;
$query = new CGI;
print $query->redirect($url);

Not really a Perl question, but hey.

The usual method is to include a unique identifier string as a hidden
field in the submission. The receiving page can query the database to
see if that unique string has been submitted already; if so, scold the
user for double-clicking.
