I want to leverage browser caching to increase page speed. I've done some research on this and it sounds like max-age and and last-modified are good choices, but I'm unclear on how to determine which files I should implement for it. In general, I'm confused on how to actually do this and what the code would look like in my htaccess. I guess I'm looking to get some more explicit help or to be shown some examples. Or maybe someone can direct me to a lesson/tutorial on this that a novice like me can understand, which I haven't had any luck finding. Any help from someone who knows more about max-age and last-modified and can help tell me how to do this would be greatly appreciated.
