I would like to let browsers cache my whole website, but only download the new information when I have changed one or more files.
After some research I have found a way to do this. That is to add a
Far Future Expires Header to my htaccess file and add a querystring to my files using the
When I click on the address bar and type in my website address in firefox, then Firebug displays
38.3 KB (36.4 KB from cache)
When I press F5 in firefox, then Firebug displays:
241.1 KB (10.9 KB from cache)
Now I have tried to do the same with Google and they are sending HTTP header 304 back. I have read a lot about ETag and the Last Modified header, but I have heard a lot of people saying that they are not really reliable.
What would be the best solution if I would like to send HTTP header 304 back if the user presses on F5, like Google?
It seems that Firefox is controlling the way the cache is used and I would like to use the cache also when a user presses F5.
