1458147 - Raise static resources cache max-age from 60s to 1y

Status: RESOLVED WONTFIX

(Participation Infrastructure :: Phonebook, enhancement)

Description

[:Atoll]

Right now, Mozillians uses a max-age=60 cache header; this incurs a significant network request penalty on user agents and the server, unnecessarily using bandwidth to redeliver content that does not frequently change.

We recently altered BMO to serve static assets from a versioned directory (/static/1/images/blah.jpg, with 1 incremented by developers when assets are modified) so that resources can be cached forever:

https://bugzilla.mozilla.org/static/v20180426.4/skins/standard/enter_bug.css

Cache-Control: public, max-age=31536000
ETag: "180b2d7-a33-56ac2081ef700"

Consider altering Mozillians using any appropriate method to provide permanent URLs for a given release's static resources, so that they can be served with max-age=31536000.

We found this reduces the # of requests for a page-load of BMO from 20+ 200/304 responses per page to 0 per page load once proper caching is in place.

Thank you for this feedback. We are in the process of redesigning Mozillians.org and are therefore holding off from non-critical fixes. 

Regardless of this we are thankful for your feedback.

Best regards,
