The Err_Cache_Miss error occurs when data, sent from your browser to an online server, is interrupted. The data is usually required for the page to load properly, but this will require the data to be transferred again, which is not always appropriate.
For example, if you purchase an item and just completed a form with your payment information, the data may be submitted twice (which may result in two transactions). This is why Google Chrome's caching system alerts you with the Err_Cache_Miss error.
Users may encounter the ERR_CACHE_MISS error indicating that there is a new form submission. This usually means that the web page you are viewing requires data submission to continue. Sometimes when you have already entered the data, it will need to be re-entered or the old one will be used. If this error keeps repeating, it means that there might be a problem with your current browser. Some cache items may be unusable or some configurations are not configured correctly.
