850116 - [bedrock] CDN not sending CORS header with json file

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: WebOps: Other, task)

Description

[Paul [:pmac] McLanahan]

The collusion demo is broken (bug 848527) due to the trackers.json file being ignored because of the CDN and same-origin policy. I added the CORS header to the file, which is working on mozilla.org. The CDN has gotten a new version of the file since then but is still not setting the Access-Control-Allow-Origin header.

This appears to be purely a caching issue... by adding a random query string to the second curl in comment 0 I was able to get a response that included the CORS header.

I've issued a cache purge on that one file, and it should complete in a few minutes. It appears to be working properly for me already.
