Clicking "Back" after <cflocation>

[chb_andre]

I'm using Coldfusion MX.

After a form is submitted, an "action" page is called. That page contains the
queries and stored procedures that need to be done once that form is submitted.
At the bottom of that page, I have a <cflocation> tag to redirect the user to
another webpage.

Here's my problem. Once the user is redirected to that page, clicking back
will return to the "action page" and will insert a duplicate record.

How do I stop this from happening?

Any help would be great!

Two solutions that come to mind right off are to either set some sort of flag
on the page the first time it is ran, and then wrap your inserts in logic that
evaluates how many times the page has been executed. The other would be to
query for the record and not add it if it already exists.
