If I flush the CF cache, images start to cache across my site pretty quickly and everything works great.
However, after a while they stop caching and start showing as external.
Any idea what this fix is for this? I expect some cache setting but I’m not sure as the expiry for some images is in the past (as in the image above).
Images such as the banners have no expiry but are showing as external:
For an example, the internal banner ads in /bn_img/* have the following page rule set up:
Polish: Lossless, Browser Cache TTL: an hour, Cache Level: Cache Everything, Edge Cache TTL: an hour
Thanks in advance!
