I think it's still a good idea to do form validation on the server side
also -- the client might have JavaScript turned off, for instance. Then
you've got both bases covered.
For CGI.pm, I will go through the steps to validate the data, and if
anything is bad, I will save the form data onto disk (using the method
that CGI has for saving a copy of itself), then redirect back to the
original form, with an error message, and reloading the CGI object from
disk so the data the user entered is already entered and they need only
correct the bad data.
