# Web Provider
!!! danger "DEPRECATED"
The web provider is deprecated, please use the [api](/configuration/api.md), the [ping](/configuration/ping.md), the [metrics](/configuration/metrics) and the [rest](/configuration/backends/rest.md) provider.
Træfik can be configured:
- using a RESTful api.
- to use a monitoring system (like Prometheus, DataDog or StatD, ...).
- to expose a Web Dashboard.
## Configuration
```toml
# Enable Web Provider.
[web]
# Web administration port.
#
# Required
# Default: ":8080"
#
address = ":8080"
# SSL certificate and key used.
#
# Optional
#
# certFile = "traefik.crt"
# keyFile = "traefik.key"
# Set REST API to read-only mode.
#
# Optional
# Default: false
#
readOnly = true
# Set the root path for webui and API
#
# Deprecated
# Optional
#
# path = "/mypath"
#
```
## Web UI
![Web UI Providers](/img/web.frontend.png)
![Web UI Health](/img/traefik-health.png)
### Authentication
!!! note
The `/ping` path of the API is excluded from authentication (since 1.4).
#### Basic Authentication
Passwords can be encoded in MD5, SHA1 and BCrypt: you can use `htpasswd` to generate those ones.
Users can be specified directly in the TOML file, or indirectly by referencing an external file;
if both are provided, the two are merged, with external file contents having precedence.
```toml
[web]
# ...
# To enable basic auth on the webui with 2 user/pass: test:test and test2:test2
[web.auth.basic]
users = ["test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/", "test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0"]
usersFile = "/path/to/.htpasswd"
# ...
```
#### Digest Authentication
You can use `htdigest` to generate those ones.
Users can be specified directly in the TOML file, or indirectly by referencing an external file;
if both are provided, the two are merged, with external file contents having precedence
```toml
[web]
# ...
# To enable digest auth on the webui with 2 user/realm/pass: test:traefik:test and test2:traefik:test2
[web.auth.digest]
users = ["test:traefik:a2688e031edb4be6a3797f3882655c05", "test2:traefik:518845800f9e2bfb1f1f740ec24f074e"]
usersFile = "/path/to/.htdigest"
# ...
```
## Metrics
You can enable Træfik to export internal metrics to different monitoring systems.
### Prometheus
```toml
[web]
# ...
# To enable Traefik to export internal metrics to Prometheus
[web.metrics.prometheus]
# Buckets for latency metrics
#
# Optional
# Default: [0.1, 0.3, 1.2, 5]
buckets=[0.1,0.3,1.2,5.0]
# ...
```
### DataDog
```toml
[web]
# ...
# DataDog metrics exporter type
[web.metrics.datadog]
# DataDog's address.
#
# Required
# Default: "localhost:8125"
#
address = "localhost:8125"
# DataDog push interval
#
# Optional
# Default: "10s"
#
pushinterval = "10s"
# ...
```
### StatsD
```toml
[web]
# ...
# StatsD metrics exporter type
[web.metrics.statsd]
# StatD's address.
#
# Required
# Default: "localhost:8125"
#
address = "localhost:8125"
# StatD push interval
#
# Optional
# Default: "10s"
#
pushinterval = "10s"
# ...
```
### InfluxDB
```toml
[web]
# ...
# InfluxDB metrics exporter type
[web.metrics.influxdb]
# InfluxDB's address.
#
# Required
# Default: "localhost:8089"
#
address = "localhost:8089"
# InfluxDB's address protocol (udp or http)
#
# Required
# Default: "udp"
#
protocol = "udp"
# InfluxDB push interval
#
# Optional
# Default: "10s"
#
pushinterval = "10s"
# InfluxDB database used when protocol is http
#
# Optional
# Default: ""
#
database = ""
# InfluxDB retention policy used when protocol is http
#
# Optional
# Default: ""
#
retentionpolicy = ""
# ...
```
## Statistics
```toml
[web]
# ...
# Enable more detailed statistics.
[web.statistics]
# Number of recent errors logged.
#
# Default: 10
#
recentErrors = 10
# ...
```

### Deprecation compatibility
#### Address
As the web provider is deprecated, you can handle the `Address` option like this:
```toml
defaultEntryPoints = ["http"]
[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.foo]
address = ":8082"
[entryPoints.bar]
address = ":8083"
[ping]
entryPoint = "foo"
[api]
entryPoint = "bar"
```
In the above example, you would access a regular path, administration panel, and health-check as follows:
* Regular path: `http://hostname:80/path`
* Admin Panel: `http://hostname:8083/`
* Ping URL: `http://hostname:8082/ping`
In the above example, it is _very_ important to create a named dedicated entry point, and do **not** include it in `defaultEntryPoints`.
Otherwise, you are likely to expose _all_ services via that entry point.
#### Path
As the web provider is deprecated, you can handle the `Path` option like this:
```toml
defaultEntryPoints = ["http"]
[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.foo]
address = ":8080"
[entryPoints.bar]
address = ":8081"
# Activate API and Dashboard
[api]
entryPoint = "bar"
dashboard = true
[file]
[backends]
[backends.backend1]
[backends.backend1.servers.server1]
url = "http://127.0.0.1:8081"
[frontends]
[frontends.frontend1]
entryPoints = ["foo"]
backend = "backend1"
[frontends.frontend1.routes.test_1]
rule = "PathPrefixStrip:/yourprefix;PathPrefix:/yourprefix"
```
#### Authentication
As the web provider is deprecated, you can handle the `auth` option like this:
```toml
defaultEntryPoints = ["http"]
[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.foo]
address=":8080"
[entryPoints.foo.auth]
[entryPoints.foo.auth.basic]
users = [
"test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/",
"test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0",
]
[api]
entrypoint="foo"
```
