Details

Currently some pages under /security/ don't get styled due to 404 Not Found at responsive-bundle.css: https://www.mozilla.org/media/css/responsive-bundle.59b379cf54d1.css X-Backend-Server: 0ed17530e017.bedrock-prod.us-west.moz.works https://www.mozilla.org/en-US/security/advisories/ X-Backend-Server: 8b25b773b686.bedrock-prod.us-west.moz.works https://www.mozilla.org/en-US/security/known-vulnerabilities/firefox/ X-Backend-Server: 1b1cfa93da60.bedrock-prod.us-west.moz.works Those page caches are supposed to expire every half an hour, but the pages are still broken after waiting for 1 hour. Something is going wrong?

I think this is due to the advisories pages sending last-modified headers and the CDN nodes checking that to see if they should update the cache. If the HTML becomes stale because the CSS changed and therefore got a new hash in the file name, the old filename could go missing if the CDN node cleared old cache. I'm going to have those pages stop sending the last-modified header as our use of CDN obviates its usefulness, and also it's wrong because it's not taking other HTML changes into account.

I will be investigating ways in which we can more efficiently use our CDN caches. https://github.com/mozilla/bedrock/commit/a7dfb112cc05cbb047d69e27970047ad04d793ff Merge pull request #4723 from pmac/remove-last-modified-headers-security-advisories-1344381 Fix bug 1344381: Disable last-modified headers from security pages
