How to Prevent Duplicate Submissions After Form Refresh?

Preventing Duplicate Submissions with Refresh Handling

In web development, it's common to encounter the issue of duplicate submissions when a page is refreshed after a form submission. To address this, consider the following approach:

Imagine having a code snippet that looks something like this:

When you submit this form, the provided data is inserted into the database, and a success message is displayed. However, if you were to refresh the page, the data would be re-submitted to the database.

Solution: Redirect After Submission

To avoid this duplication, it's crucial that after the operation is complete, you do not display the response on the same page. Instead, redirect to a new page.

By redirecting after the submission, you ensure that refreshing the page will only trigger the GET request for the new page that you redirected to, preventing duplicate submissions.
