If you need to support multiple virtual hosts for a container, you can separate each entry with commas. For example, `foo.bar.com,baz.bar.com,bar.com` and each host will be setup the same.
### Backup Server
Sometimes it is necessary to mark a containers as [backup server](http://nginx.org/en/docs/http/ngx_http_upstream_module.html#server). To achieve this, set the environment variable `BACKUP_SERVER=true`.
### Wildcard Hosts
You can also use wildcards at the beginning and the end of host name, like `*.bar.com` or `foo.bar.*`. Or even a regular expression, which can be very useful in conjunction with a wildcard DNS service like [xip.io](http://xip.io), using `~^foo\.bar\..*\.xip\.io` will match `foo.bar.127.0.0.1.xip.io`, `foo.bar.10.0.2.2.xip.io` and all other given IPs. More information about this topic can be found in the nginx documentation about [`server_names`](http://nginx.org/en/docs/http/server_names.html).
