What does ctrl f5 do
Ctrl F5 (or Ctrl + F5) reloads the current page including the browser cache. It’s called Hard reload.
It means that the browser will not use the current cache but will be forced to download again all the files (js files, images, scripts, …). You will have the most fresh version of the page sent by the server.
On Apple / MAC, the shortcut is Command R (Command + R).
This behaviour will be the same on all web browsers.
