The idea is that the browser tries to avoid redownloading these static files of the web page to make the page load faster. When a “Normal Reload” is performed browser will use the cached copies of static files(CSS, javascript, images, text files) of the web page that were downloaded during the first load event of that web page. “ Normal Reload” is performed in a web page loaded in a browser like chrome by pressing the reload button in the top left corner of the browser next to the back & forward button or by pressing the keyboard shortcut Ctrl+R or using function key f5. To understand “Hard Refresh”, you have to first understand what happens during a “Normal Reload”.
Ctrl+Shift+R is a keyboard shortcut used to perform a hard reload of a web page in Google chrome.
