Edit response header in EDS | Community

Hi ​@abid22 

Not in Edge Delivery itself. The Vary header you're seeing on Edge Delivery pages is effectively service-managed/OOTB, and there isn't a supported way to change those values from the Edge Delivery project/app layer. Internal guidance for similar cache headers is explicit that Edge Delivery does not expose header customization there; if you need different behavior, the supported place is the CDN layer.

Just to add: since this is managed at the Edge Delivery layer, any changes would need to be handled at the CDN level (e.g., cache key / header handling), rather than in the EDS app itself.

 

Worth keeping in mind that adjusting Vary-related behavior can impact caching efficiency depending on the setup.

 

Curious if this is more for cache optimization or controlling response variations?
