Google Chrome is an awesome browser with great security features to protect our private data from miscreants and hackers on the Internet. But unfortunately, we may run into some errors sometimes, like this ‘confirm form resubmission’  or ‘ERR_CACHE_MISS’ error. But you don’t need to worry about these errors as they are not of a serious kind and also they can be claimed as a security feature in the browser.

What does Confirm Form Resubmission mean?

In simple terms, the ‘confirm form resubmission‘ error is usually faced when a user tries to submit any kind of data through a form on a website. You will get the confirm form resubmission prompt if you refresh a page right after you submitted some type of data through a POST action and as you refresh the data, it causes the data to be resubmitted. It is an error or a misfeature or a security feature which primarily occurs in the popular web browser Google Chrome.

When you send a POST request by submitting a form or entering any kind of data on a webpage, that data is transferred to a database. Now Google says that they introduced this confirm form resubmission dialog in the Google Chrome browser to avoid sending duplicate requests to the database in order to avoid duplication of data.

This feature will also prevent or save you from paying for the same thing twice because there can be times when we entered our payment information but for some reason, the next page isn’t loading and so we press the refresh button but this can be dangerous and result in us getting charged two times. So the prompt was introduced to prevent this from happening. This error also sometimes presents itself with the error code – ‘ERR_CACHE_MISS‘.
