Content passing through auth-proxy should remain gzipped

Gzip is enabled in nginx for all the front-end projects, but assets are being delivered to browsers with no content-encoding. My guess is that this related to an auth-proxy setting (though the problem could in fact lie elsewhere).

Hmm. Actually my initial theory doesn't make sense as of course auth-proxy is still in effect in the local setup where the content encoding is being properly set. So either it is change introduced in deployment or a different part of the stack.

Hmm#2. In retrospect I don't think auth proxy actually touches these requests for static files at all. So..! This issue can probably be closed, but I'm going to leave it open until I'm on the right track.
