Avoiding form post multiple times

Question

I have clarification regarding the form submit. When a page is submitted and again, when we refresh again, I should not post it again.

How can I do it? How can I avoid the user from submitting the form again?

It may be refresh or anything which allows the user to submit the form again.

On the front end, you could disable the submit button after submission.

On the server side, you could assign a unique id or generated random key which you could check for duplicates.

One thing what you can do is that in your server, you can look for the ip address from which the request is coming and have a specific interval set between similar requests are sent from the same user.

If you are using PHP, you can look for in $_SERVER['REMOTE_ADDR'] to get the ip address.
