<title>Redirecting...</title>
<h1>Redirecting...</h1>
<p>You should be redirected automatically to the target URL: <a href="http://localhost:8080/airflow/">http://localhost:8080/airflow/</a>. If not, click the link.
```

### What you think should happen instead

At least not circular redirect.

### How to reproduce

generate yaml:

```
helm template --name-template=airflow  ~/downloads/airflow > airflow.yaml
```

add base_url in webserver section and remove health and ready check in webserver(to keep pod alive):
```
    [webserver]
    enable_proxy_fix = True
    rbac = True
    base_url = http://my.domain.com/airflow/
```
