The most common way I've seen is by disabling the submit button. If your
audience uses strictly IE, then you can use JavaScript to actually disable
the button making it so that the button can no longer be pressed. If you
have a mixed set of users, you can change the submit button to a "button"
button and use JavaScript to submit the form as in:
<SCRIPT LANGUAGE="JavaScript">
<!--
var formSubmittedInd = 0;
function submitForm() {
if (formSubmittedInd == 0) {
formSubmittedInd = 1;
document.myForm.submit();
} else {
alert("Patience is a virtue.");
}
}
// -->
</SCRIPT>
<INPUT TYPE="Button" VALUE="Submit" onClick="submitForm();">
Also, make sure that your confirmation screen is different from the actual
action page as in:
form.cfm (submits to) action.cfm (forwards to) success.cfm
This way, when the user is looking at the success/confirmation message, if
they hit refresh, the action.cfm page is not executed again.
