I guess you should probably check the accept headers of the request, that
they are OK w/ application/zip:
`req.getHeader(HttpHeaders.ACCEPT)`. You could check w/ guava's
`MediaType#is` (I couldn't find a simpler way ...)
```
val accepts = MediaType.parse(req.getHeader(HttpHeaders.ACCEPT))
if (MediaType.ZIP.is(accepts)) {
...
}
```
