Enonic XP: Image caching

Help
1

XP 5.3.0 does not return any cache headers for images, any reason for this ?

Ex:
http://localhost:8080/portal/master/unox/privat/_/image/216cc098-535c-4728-8254-553623ba1ea5/unox_sykkelglede.png.jpeg?filter=scaleBlock%28800%2C+490%29

Hi Tommy!

This appears to be a bug. We’re looking into it. Hope to include a fix in 5.3.1 (which is just around the corner)

Hi Thomas,

Were you able to include this in 5.3.1 that was just released (can’t see it in the change list) ?

Hi. This was postponed to 6.x due to the fact that implementing the image-caching without proper automatic invalidation would case a lot of other issue with images not being updated as expected when changing. But its not forgotten, just postponed a short while to make room for a much better solution.

Hi!

Glad to report that perfect cache is now implemented for images, attachments and assets in 6.2 (ETA < 14 days)
