disabling gzip if etag exists in proxy_pass response

Question

I'm new to nginx.

Is there a way to disable gzip if proxy_pass reutrns the ETag header.

I.E:

gzip on;
.
.
.

    location /foo/bar {
      proxy_pass http://server:123;

      if ($upstream_http_etag) {
         gzip off;
      }
    }

Basically I'm looking for a workaround to this bug that will disable the gzip compression if server responded with etag header.

Thank you, Vitaly

Answer 1

There is now, gzip_proxied has no_etag parameter:

gzip on;
gzip_proxied no_etag;

The bug is closed, too.
