WP_AJAX includes no-cache headers with its responses. I'm using Ajax to fetch part of a shopping cart, which includes little image thumbnails. On each Ajax request, these are replaced and we can see them window-shading down, which looks wack and wastes bandwidth. Is there a way that those images can be cached without caching the whole response?

I can filter the headers, or adjust the Ajax call, or maybe do something downstream at CloudFlare, but this isn't my area of expertise and could use some help. Thanks!
