Issue/Request:

Hi Yalesites Crew,

I have to manually attach a query string to get the latest content on pages for the above site.

This is true even with a fresh device (phone, etc.) that hadn’t accessed this site previously.

I have hit the admin ‘Flush all caches’ item, the ‘page and else’ item, and the button on admin/config/development/performance.

Thanks in advance!
Mike

Hi Mike,

Is this now displaying the current content or did it not work after you flushed the cache from the admin menu?

Guys, it looks like the drupal cache tries to do the right thing…

But maybe the vendor has an edge cache that is being greedy for anon users?

ANON: I see x-cache: HIT even with x-drupal-cache: MISS

CAS: I see x-cache: MISS

(and the anon cache setting in Performance must be watchdogged because it won’t accept changes)
