Use the PRG pattern (Post/Redirect/Get).
Implementing the Post/Redirect/Get (PRG) pattern is one well-liked method for avoiding the "Confirm Form Resubmission" problem. The steps in this pattern are as follows:

You are not the only one who receives the "Confirm Form Resubmission" problem warning when you reload a page. The browser asks you if you wish to resubmit the form data when you attempt to refresh a page that was accessed through the submission of a form. Although the purpose of this action is to preventConfirm Form Resubmission, users may find it annoying. Fortunately, there are a few ways to correct this mistake.

Use the PRG pattern (Post/Redirect/Get).
Implementing the Post/Redirect/Get (PRG) pattern is one well-liked method for avoiding the "Confirm Form Resubmission" problem. The steps in this pattern are as follows:

1. Ask the server to take care of form submission.
2. Direct the user to another website using the HTTP redirect (HTTP 302) status code after a successful form submission.
3. The user is then transferred to the new page; reloading the page will not cause the form to be submitted again.

If you carry on in this manner, the website will need to be completely reloaded to prevent the browser's history from being updated and the resubmission confirmation from appearing.

2. Submit the form using AJAX.
Another option is to enter data using AJAX (Asynchronous JavaScript and XML). You can send form data to the server asynchronously using AJAX without refreshing the browser. By doing this, the form data is submitted in the background and the confirmation of a resubmission is not displayed when the page is refreshed.

You can implement this concept by handling the AJAX request using JavaScript and a library like jQuery. Use AJAX to transfer the data to the server when submitting the form rather than the standard form submission process. You can dynamically alter the page's content after the server has finished processing the request to avoid getting the "Confirm Form Resubmission" error.

3. Implement the Post-Redirect-Get (PRG) Design Pattern.
The Post-Redirect-Get design pattern, which is comparable to the previously stated PRG pattern, is another approach for dealing with the resubmission issue. The steps in this pattern are as follows:

1. Ask the server to take care of form submission.
Save the relevant information in the server's session or database if the form submission is successful.
3. Change the user's desired URL.
4. Obtain the saved data and enter it on the page that was redirected.

Reloading the page won't result in the resubmission confirmation when you apply this pattern because the form data isn't saved in the browser's history.

Fourth, use client-side data storage.
You can use client-side data storage solutions like Web Storage (localStorage or sessionStorage) or IndexedDB if you're dealing with contemporary web technologies. You can use one of these storage methods to preserve the form data locally in the browser rather than depending on form submissions. You may then retrieve the saved data and pre-fill the form fields to avoid the requirement for a new submission when the user reloads the page.

Conclusion
Even though the "Confirm Form Resubmission" problem can be annoying, there are numerous ways to fix it. You can offer a smoother and more user-friendly experience on your websites by adopting techniques like the Post/Redirect/Get pattern, AJAX for form input, or client-side data storage. Select the approach that best satisfies your needs, then properly implement it to solve the problem and improve your customers' surfing experience.
