Wondering what everyone does to prevent multiple form submissions?
My form is simply getting emailed to my email, and it redirects to a success page when submitted...
Would it be as simple as doing something with the cache control? Basically I'm trying to avoid someone submitting a form... Then hitting back, and submitting again, then hitting back.... I think you get the idea...
What do you all do?

Hi,
I am using $_SESSION for this. Set a value on the initial page, a
timestamp is a good choice, then validate the value on the receiving
script and clear the value.
I like to use a timestamp because it will allow you to deny a comment
which took too long to submit.
