Most of the other special cases have the following lines as well:

```
expires -1;
proxy_next_upstream error http_502;
proxy_pass http://tenantworkers;
```

Do we need to add these here as well? We might be able to remove `expires -1` on all of the POSTs at least, as they shouldn't be cached anyway. Also, is there a way in which we can apply `proxy_pass http://tenantworkers;` to all of them without having to repeat it in every block? /cc @mrvisser
