I find out that whenever I do window.location.reload(), the requests for the images on my web page is sent to the server. The images are cached with an expiry date, thus I think they should be loaded from cache instead. Because all I get from the server is 304 unmodified, I have a lot of images on the page so I don't want a request for each image when the page refreshes.
My question is why is the browser try to contact the server instead of loading them from cache?
Thanks!
304 Not Modified indicates to the browser that it should reload from cache. If you look at the bytes sent it should be less than 1kb when reloading from cache.
