When using _whitenoise_ for caching, which provides compression, binary types may include mimetypes, "text/", "application/json":

- response.mimetype.startswith("text/")
- response.mimetype == "application/json"

Assuming that Content-Encoding will be set (as whitenoise apparently does) this allows compression to be applied by the application for "text/" and "application/json".

About Content-Encoding:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Encoding

Use Content-Encoding to identify if data is binary

Include fallbacks for cases:
- try binary, fail to text
- try text, fail to binary
