@aledsage the existing Nginx tests are sufficient to verify there are no
regressions, however the use-case for this code is no longer as urgent. It is
still a useful change, since it supports HTTP 1.1 and connection upgrades
properly now, and the code is also more readable.
The change to the config file that adds this is the addition of these two
groups of lines:
```
map $http_upgrade $connection_upgrade {
default Upgrade;
'' close;
}
```
```
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
```
