My completely unresearched educated guess is that Ctrl+F5 generally refreshes the page without using cache while Ctrl+R or plain F5 refreshes the page using cache as normal. – MooGoo Oct 30 '10 at 20:42

Ctrl+F5 does indeed do a force cache purge for that page, while Ctrl+R does not.

@Infestor, in Firefox F5 and Ctrl-R are the same. Ctrl-F5 and Ctrl-Shift-R are the same too. Of course, that's only one out of many browsers. – Arjan Oct 30 '10 at 22:59
    
(As an aside: using F5/Ctrl-R might make a browser still ask the server if the content has changed by using If-Modified-Since headers, hence still leaving it up to the server to serve new content or not. Hitting Ctrl-L to get to the location bar and pressing Return, or selecting a bookmark makes most browsers rely on their cache without asking the server about any changes.) – Arjan Oct 30 '10 at 23:08
    
@Arjan is this the same for Chrome? Like it is in FireFox? – Kevdog777 Apr 29 '13 at 15:03
    
Yes, @Kevdog777, you can check using the developer tools (Option+Command+I on a Mac, and then peek into the Network pane). But in case you're asking as you're having problems with Chrome's cache, then see another answer. – Arjan Apr 29 '13 at 17:13
