Page Redirection

I have a processing page (act_process.cfm) that does an insert into the DB. Once somebody reached this page I want to make sure they don't click the "back" button in the browser and re-submit. Does anybody know how I can get around this? Thanks...

Disabling the back button is not a good approach. There should be a trigger somewhere that prevents duplicate submissions. A javascript function that is called before the form is submitted would work. When the function is called it checks a variable to see if it equals 0 and only submits the form if it does, and then sets the variable to 1, so that the form may not be re-submitted without refreshing the page.

<SCRIPT LANGUAGE="javascript">
formsubmitted=0
function chkform(){
if(formsubmitted==0){
formsubmitted=1;
return true;
}else{
alert("Form has already been submitted!");
return false
}
}
</SCRIPT>

<FORM ONSUBMIT="return chkform()" ...

One Better Idea what I can suggest is that, before INSERTing into the table, first try to select that record with the keys, then check the recordcount.

If recordcount is greater than 1 then don't insert, else insert into the table.
