This pull request adds a
Vary: X-Requested-With
header to Control Panel responses.This fixes an issue with the Users listing page on Chrome. If you go onto the users listing table, do any kind of filtering, click on a user, then use the browser back button, you'll see a JSON response instead of the listing page.
This was only happening on the Users listing because it's the Blade view & JSON responses share the same URL, where our other listing pages have separate URLs.
From what I can tell, I believe this issue is only affecting Chrome(ium). The
Vary
header seems to tell the browser which headers cause a different response to be returned - theX-Requested-With
header is different between the two types of requests so it fixes the issue.Fixes #9937.
