8 Ways to Fix Confirm Form Resubmission Err_Cache_Miss Error

The confirm form resubmission ERR_CACHE_MISS notification shows up in your browser when you hit Refresh or try to go back.

This is the entire notification message that you will see on your screen:

To protect you from inadvertently doing the same POST actions many times when you are filling out forms, Google Chrome now displays a pop-up that says confirm form resubmission. It might be a hassle to fill in the same information repeatedly or to submit the same thing many times.

If you reload the page, even if the error does not appear, it is possible that your credit card may be charged twice. Whether you refer to it as a pop-up or an error, the fact remains that it appears only for your benefit.

What does it mean when it says confirm form resubmission?

NOTE

You can only fix the confirm form resubmission on the refresh/back button with this method if you can edit the page.

6. Replace the POST method

The information you entered on the web page is posted using either the POST or GET methods.

While the POST method doesn’t append your entry to the URL, the server wouldn’t have access to your data.

On the other hand, the GET method appends your entry to the URL. Hence, your data isn’t as secure as the POST method.

If you can modify the page data, you can fix the confirm form resubmission issue by changing the POST method to the GET method.

To do this, simply remove the POST from the page URL and replace it with the GET method. For example, if the original code is:

<form action="index.php?load=SUBMIT"method="post">

you can replace the post part to get, so it becomes:

<form action="index.php?load=SUBMIT"method="get">

This solution is intended for web developers, and by making this change you should be able to fix the problem with Confirm form resubmission message.

7. Make use of Ajax submit button

Use the following snippet for the submit button to disable confirm form resubmission:

$.ajax({

data: dataString,
success: function(){
//Insert your submission action
}
});
return false;

Whenever you see the confirm form resubmission ERR_CACHE_MISS message on your browser,  you can simply click Continue. However, if you do not wish to resubmit the form data, click on Cancel.

How to prevent confirmation form resubmission?

Making your form utilize the GET method rather than the POST method is one approach to get rid of this error notice. Bear in mind, however, that this is not the best course of action in every situation.

Always utilize the POST method when executing an action that you do not want to be repeated, when transferring sensitive information, or when your form includes either a file upload or the length of all data provided is larger than 2000 characters.

You do not want the page to be refreshed and the data to be resent in any of these scenarios. If you are sending sensitive information, using GET would not only be inappropriate, but it would also be a security issue.

This is because the sensitive item (such as the user’s password) is sent in the URL, and since it is sent in the URL, it will therefore show up in server access logs.

You should use GET for anything else: when you don’t mind if it is repeated, for anything that you could provide a direct link to, when no sensitive information is being transferred, when you are pretty sure your URL lengths are not going to get out of control, and so on.
