Matrix Version: 22.214.171.124
Edge and MAC both seem to prevent all Matrix pages from ever being cached in the browser regardless of the Cache Manager settings.
Example - set up page with a Cache manager override set to Browser Cache for 10mins and Accelerator Cache for 60mins. When you request this page via Edge or MAC it will be served with the header
Cache-Control: private, max-age=0.
I think this is due to Edge Side Includes (ESI), the logic being that you want the final caching to happen at the layer that is doing the final composition of the page. That way if you’ve got your left nav included via ESI and you updated it, users can get it immediately instead of seeing a browser cached copy. The issue is that it appears to override the desired browser cache setting even for pages that don’t have any ESI tags.
There are times when you really do want browsers to cache a dynamically generated response for some short period to avoid unnecessary overhead on every page (not to reduce traffic at the server, but at the client). Is it possible to get this behaviour again for a site behind Edge/MAC? (without throwing out the current behaviour on pages where you want it)
