difference between reload and refresh?

[niche]

What can be generally said about the difference between reloading a page (ie header()) and simply pressing the refresh button?

Maybe, reload do load of whole page again, but refresh only reloads parts which are changed, and those which are not, doesn't reload.

The use of the terms is a bit sloppy, but just telling the browser to load a page again (e.g. through a loopback redirection) will cause it to fetch as many resources as it can from the cache, but if the client invokes a refresh/reload, all cached resources are cleared and downloaded again. Note that in many browsers, just pressing "refresh" actually just loads the page again, and there is another command for a true cache-clearing refresh.

What terms would you use instead of refresh and reload?What's the command for true cache-clearing?

[Synook]

Uh, "load again" and "refresh" I suppose .On Firefox I believe the hotkey is Ctrl + F5. Chrome refreshes the cache when you press refresh (but not if you go to the address bar and press Enter).

I'd use the terms "user refresh" and "header refresh" - you're still doing a page refresh, but the difference is where it is initiated from.CTRL+F5 is a universal combo across all desktop browsers for "Refresh with cache disabled". Different browsers behave in all sorts of strage ways depending on the other ways users do a user refresh, but a header refresh usually involves a refresh with enabled cache.

Thanks for everyone's help especially to Haris S, Synook and boen_robot. I realized that I was taking for granted a user's action when they and needed to ask if there was a difference between user refresh and header refresh.Niche
