I have a webserver that returns both json and pbf. I am using etag to allow caching. This works fine for both json and pbf on chrome but not on firefox. Firefox ignores the header it seems.
I tried different caching header but none seem to work.
Here are the response+request headers for the second request (the one that uses caching) for json

Firefox doesn't support caching for file downloads such as pbf.
