F5 triggers a standard reload   Ctrl   F5 triggers a forced reload  This causes the browser to re-download the page from the web server  ensuring that it always has the latest copy   Unlike with F5  a forced reload does not display a cached copy of the page

F5 is a standard page reload  and Ctrl   F5 refreshes the page by clearing the cached content of the page  Having the cursor in the address field and pressing Enter will also do the same as Ctrl   F5

CTRL F5 Reloads the current page  ignoring cached content and generating the expected result

F5 reloads the page from server  but it uses the browser s cache for page elements like scripts  image  CSS stylesheets  etc  etc  But Ctrl   F5  reloads the page from the server and also reloads its contents from server and doesn t use local cache at all  So by pressing F5 on  say  the Yahoo homepage  it just reloads the main HTML frame and then loads all other elements like images from its cache  If a new element was added or changed then it gets it from the server  But Ctrl   F5 reloads everything from the server

F5 and the refresh button will look at your browser cache before asking the server for content   Ctrl   F5 forces a load from the server   You can set content expiration headers and or meta tags to ensure the browser doesn t cache anything  perhaps something you can do only for the development environment
