If you want to reopen the closed page in Google Chrome or Microsoft Edge browser, just use Ctrl+Shift+T to restore the closed page.
Of course, you can also find the closed page through the historical record and then reload it. Both of these recovery methods require the entire web page to be reloaded.
Google is currently working on a new method to allow users to more easily restore the closed page: the cached page does not need to be reloaded when it is restored.
At the same time, the restored page can also use the navigation button to go back or forward. Of course, this requires Google Chrome to cache the page to be able to restore and go back in seconds.
According to Google engineers, this new feature called Back Forward Cache will use the memory to cache closed pages for users to quickly restore pages.
Pages restored from memory still support back and forward, so this is indeed different from the current full reload of the page that is restored using shortcut keys.
However, the biggest problem is that this function needs to take up memory to save those closed pages, and the experience provided is that it can be opened in seconds and supports forward and backward.
Without this feature, reloading should be completely fine for users whose internet speed is not particularly slow. It seems that it might be useful if the internet speed is slow.
In addition, Google emphasizes that this feature is currently in a highly experimental state. After enabling this feature, it may cause various errors, and users need to be psychologically prepared.
Of course, if you want to participate in the test of this function, then you can trigger it via chrome://flags/#closed-tab-cache flag.
