Once the DNS cache has been cleared, we should also clear the navigation cache where the files downloaded locally are contained to speed up navigation, to do it in chrome there are various methods:
- Menu (the three dots) select the item Other Tools and then Clear Navigation Data, we can also use the quick keys Ctrl + Shift + Del on Windows or cmd + shift + backspace on macOS
- By installing a Chrome extension: Clear Cache , highly recommended when administering your own ecommerce or website, in order to check correct loading after new changes. The cache may not only not show the last change, but hide problems introduced with it.
Other very useful extensions when managing your own e-commerce in PrestaShop are:
- EditThisCookie , allows you to delete cookies in order to view PopUps set to be seen only once or in case of problems with login and carts during any tests with different users.
Notes : the navigation cache requires us to design and study the changes in a targeted way avoiding improvising and continuing to make structural changes, such as new modules and features or removing already activated functions, especially when the modified code is client-side such as JS script . For example, if we decide to no longer ask customers to confirm the terms and conditions of purchase, those who locally in the cache have the old setting if they do not reset the cache will not be able to complete the order anymore, because the recalled JS will not be the same. new provided by our server, but the old one still locally on the client's computer. When it comes to an ecommerce, everything must be planned and considered.
