Put a unique identifier in the form request, store it in the user's
session before form submission. Once the form is submitted check to
see if the value matches. If so delete it from the session and
continue processing. If the token doesn't match or is nonexistent in
the session, then its a duplicate or out of order submission.

I'm working on an application where a form is submitted along with
various attachments (doc, pdf, xls, etc). Apparently users are
submitting the same request several times and I've been asked to
address this issue. At first thought, it seemed quick and simple to
me, but as I've started working on it I can't decide exactly how to
handle the attachments in associated with the form in the most
efficient way.
That brings me here. I was looking for suggestions on how to handle
the attachments while I run validation on the db to see if the input
from the form already exists in the db. It seems like something
that would be perfect for AJAX to handle, but my AJAX skills are
virtually nonexistent. So, without using AJAX (or if you can break
it down using AJAX for a novice) how would you handle the situation?
The main issue I'm having, is that if I do the validation after the
form submission, CF is assigning a temp directory to my attachment
file. So what is submitted as this: "C:\Documents and Settings
\JHoward\Desktop\PO Request mods.doc" ends up as this after
submission and validation: "C:\ColdFusion8\runtime\servers\coldfusion
\SERVER-INF\temp\wwwroot-tmp\neotmp13963.tmp " and then when I pass
it to the CFFILE, it tells me the file doesn't exist.
I'm really just looking at the different ways other people would
handle this situation to try and decide so any input would be great.
Thanks in advance.
