After a form is submitted, I want to keep the user from using the [browser back
/javascript history back] function to access the form with the fields populated
to avoid a second submission. User must complete the form from scratch each
time it is submitted.
This is fairly problematic, depending on how much control you have over the
users' browsers and its settings.
The best method I've heard of is to provide an unique ID value to each form
presented in a hidden field, and then only allow one submission per form ID
value.
Something along these basic lines:
<form....>
<input type="hidden" name="formUniqueKey" value="#generatedUniqueValue#">
Action Page
If form.formUniqueKey has already been submitted.
You have already submitted this data, please refresh your form and
submit again.
Else
Process form once and only once.
