Use with CDN #
If you use CDN(such as Cloudflare) for your website, we’d recommend you to add a private
header like the example below, this will prevent your images from being cached and webp images rendered to Safari users(which will of course cause some troubles).
Cloudflare #
Cloudflare will cache all the images(by extension) from your website, which will the webp
format of the image and use it for all visitors, which the cached image cannot be shown on Safari browser.
So you need to add a custom header to prevent Cloudflare from caching those images, like this:
location ^~ /wp-content/uploads/ {
add_header Cache-Control 'private';
proxy_pass http://127.0.0.1:3333;
}
