http://gerrit.cloudera.org:8080/#/c/3462/1/.htaccess
File .htaccess:

Line 1: # Don't cache content or styles / scripts served by us.
I forget, do we serve our own bootstrap/etc? or use a cdn?


Line 5:      Header unset ETag
why not use etag based caching?

File .htaccess:

Line 1: # Don't cache content or styles / scripts served by us.
> I forget, do we serve our own bootstrap/etc? or use a cdn?
Mostly CDN, but it's a mix. We should probably try to get more from a CDN. e.g. right now we serve bootstrap, but jquery is on a CDN. If we had our own CDN, we could also put our own (versioned) files up there and have it cache the files indefinitely.


Line 5:      Header unset ETag
> why not use etag based caching?
ETags are not distributed; different servers will give different ETags for the same content. Since the upstream site appears to have mirrors (based on nslookup) then I don't think ETags will work. See also https://developer.yahoo.com/performance/rules.html#etags=

However I didn't do a thorough investigation of how ASF load balancing is set up.
