# Example
## Adding a custom ban page
Traefik can return a custom HTML ban page along with the 403 HTTP response code.
This can be usefull as some browser (Firefox for instance) return a 403 blank webpage and we can mistake a server/reverse-proxy error with a ban from Crowdsec.
### Traefik configuration
```yaml
labels:
# Define ban HTML file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaHTMLFilePath=/ban.html"
```
The ban HTML file must be present in the Traefik container (bind mounted or added during a custom build).
It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/ban.html) it locally to expose it to Traefik.
```yaml
...
traefik:
image: "traefik:v2.11.0"
volumes:
- './ban.html:/ban.html'
...
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type ban
```
![image decision ban](image_decision_ban.png)
We will see in the browser the ban custom page:
To play the demo environment run:
```bash
make run_custom_ban_page
```
