We are living in a fast-moving Internet age and in order to ensure that we continue moving at that fast pace, a lot of things have to run and perform operations correctly to make that happen. Unfortunately, we may run into some unfortunate errors sometimes, like this “confirm form resubmission” error which many users of Google Chrome are facing.
This is a very serious kind of error which occurs when we are submitting some kind of data through a form and the function the form is using to submit the data is POST. This error has been reported many times on different popular forums such as Superuser, Stackoverflow and Google Product forums. A user on the Superuser forum claims that the module which handles this backward and forward operation is so badly coded that the engineers at Google are afraid to rewrite it from scratch.
The “confirm form resubmission” error or the “Err_cache_miss” error occurs on multiple websites where you perform actions like:
- When you are purchasing anything online and after entering your credit card info suddenly your browser shows as “Confirm Form Resubmission”.
- Filling out a contact us form on a website.
- Filling out your pieces of information on different kinds of website forms which involves some kind of editing on the database, then you might also see this error.
- Mostly happens when you submit a form with the method “POST” which then also posts back the same page and when you press enter again from the URL bar, it shows “Confirm Form Resubmission Error”.
- Sometime even due to some cache errors you might end up adding the thing you want to buy two times in your cart. This error also occurs at this time.
What Is Confirm Form Resubmission?
It is an error or a misfeature which primarily occurs in the popular web browser Google Chrome, sending a POST request when submitting a form or pretty much just entering some kind of data to be transferred to a database. Google says that they introduced this feature in their web browser Chrome which automatically makes users avoid duplicating a POST request while entering data in a form on a website.
What Does Confirm Form Resubmission Mean?
What it means is it is an error or more correctly is a misfeature from Google Chrome which appears or prevents users from accidentally reproducing POST actions on data submit forms. A simple example of this would be entering your email address twice while entering it on a website newsletter form or simply buying stuff twice mistakenly while purchasing something online. The error may also appear as ERR_CACHE_MISS sometimes and it can be pretty annoying. Some users claim that this is a security feature from Google and it prevents users from mistakenly purchasing a certain thing twice and saves you money.
A simple example of this error or feature would be, Lets suppose you are buying a book from an online store and when entering your shipping and billing address on the website form, a POST request is usually sent from your browser to the website and when information is successfully received by the website, it sents a success HTML response. Now if you press the submit button twice and the developers of the website have done a good job, then the odds of ordering the item twice is pretty low but you can’t always trust someone you don’t even know. So here comes the feature “Confirm Form Resubmission”, which will save your money and prevent you from getting charged twice for the same thing. Refer to WPShout for more on this topic.
How To Avoid Confirm Form Resubmission?
Well, there are several ways in which you could prevent this “Confirm Form Resubmission” warning from appearing again. Below are a few methods which are listed in order for you to solve this annoying error –
1. Avoid Confirm Form Resubmission In Php –
Get into your code and look for this specific piece of code, which is a POST function and this is the main cause of the problem.
<form action=”index.php?load=SEARCH” method=” post”>
Then replace that line of code with this GET function and you will see that you are no more getting this error from Google Chrome.
<form action=”index.php?load=SEARCH” method=” get”>
2. Another Method Via Php
There is also another method which can be used to avoid this error from presenting itself again and again. You have to add these two lines of code at the beginning of your code.
<?php header("Cache-Control: no cache"); session_cache_limiter("private_no_expire"); ?>
3. Adding a Phraze along with Chrome.exe
There is another way you can stop this “Confirm Form Resubmission” error from appearing, again and again, is that by adding this small phrase at the end of chrome exe. Here are the steps to do that –
- Goto your Desktop.
- Find the Chrome Browser Icon.
- Right, Click on the shortcut.
- Then Select Properties.
- In the Target Field, add “-disable-prompt-on-repost ” and then save the properties.
It should stop after that and for any help refer to the image below.
4. Disable Corrupt and MalFunctioning Extensions
There can be a lot of harmful extensions present on your browser which might be collecting your data or messing with your data, while you are browsing. Go to your extension manager and remove all the extension which you don’t use anymore or which may look suspicious. These suspicious extensions can contain malware which in turn might be spying on your network and all your online activities. So it is better to look at all the ones available and remove the unknown and suspicious ones which you have forgotten installing and you use no more.
5. When To Use GET or POST Functions?
A user from the famous forum Stackoverflow, claims to have found another solution to this problem. In order for this solution to work, you must have access to the code of the website, or you must be a developer of the website, which you can change the code of. You should try using the GET function instead of the POST function.
Use POST only when you are developing a login form, a contact form, a form which edits database entries, payment form. image uploader or a form with multiple fields which might create a very long URL. You should use GET function for virtually any other form you thing you might be building. You can use GET in performing a search in a search engine or whe performing actions which will occur only once or navigation buttons for navigating.
Disable Confirm Form Resubmission on Firefox
Firefox may also show this error sometimes, as we earlier said that this is a security feature and should not be considered as an error. Anyways to prevent “ERR_CACHE_MISS” from happening again on Firefox, just open up your Firefox settings and then the Privacy & Security tab and clear all your cache. Then restart your Firefox browser and give it a try again, this time you shall not see that error or security feature again.
