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.
