Thanks, this is a great article! One question – is there any way of getting around the max-age=0 request header that Firefox sends upon an F5 refresh? It renders all my .htaccess goodness useless. Thanks!
@Karen: Good question, I didn’t realize Firefox did that on an F5. It seems the intent is to look like an entirely new visitor upon an F5 request (i.e. I don’t have any versions of any files), so I’m not sure if there’s a way around it.

Great summary of caching, very informative and readable.
Thx for the detailed info.
But where i write the caching rules?
In a .htaccess file or in the header of the site or somewhere else?
Sorry, this is very new for me.
Regards, Michael
yes, I would also like to know where to place this info. I’m on an IIS server, so I know the rules are a little different. I am just having trouble understanding where to place, say, an http cache expires header for “logo.jpg”
This is an awesome tutorial, regardless-- THANK YOU!
