Dispatcher configuration caching issue

Hello all,

I'm having an issue with a dispatcher configuration.

The issue is exactly this one :

Dispatcher caching issue while displaying the image renditions in AEM

However, my issue is that the proposed solution cover only the thumbnail and I'm not able to find a way to use a selector with renditions, even the native web.1280.1280.jpeg rendition.

Did someone knows how to do it ?

I could write my own servlet using a custom selector that will sent the web.1280 renditions but I just think that it should exist a better / native solution to this issue.

Many thanks,

Grégory
