> The heaviest page, the marketing page, today weighs 110 KB with a cold cache, and 4.6 KB warm. (more comparisons between cold and warm loads) I set HTTP cache-control immutable on my blog's image/JS/CSS URLs this weekend. Cache-Control: immutable tells the browser that this URL will never change, so don't check to see if it has. It should cut down on the warm loads more. If it does change, the timestamp in the URL path will change, so browsers will check the new URL. https://bitsup.blogspot.com/2016/05/cache-control-immutable.html https://bitsup.blogspot.com/2016/05/cache-control-immutable.... I suggest caching the main HTML, too. It would get the total warm load down to less than 1 KB.
