# Headers
|
|
|
|
Adding Headers to the Request / Response
|
|
{: .subtitle }
|
|
|
|
|
|
|
|
The Headers middleware can manage the requests/responses headers.
|
|
|
|
## Configuration Examples
|
|
|
|
### Adding Headers to the Request and the Response
|
|
|
|
Add the `X-Script-Name` header to the proxied request and the `X-Custom-Response-Header` to the response
|
|
|
|
```yaml tab="Docker"
|
|
labels:
|
|
- "traefik.http.middlewares.testHeader.headers.customrequestheaders.X-Script-Name=test"
|
|
- "traefik.http.middlewares.testHeader.headers.customresponseheaders.X-Custom-Response-Header=True"
|
|
```
|
|
|
|
```yaml tab="Kubernetes"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: Middleware
|
|
metadata:
|
|
name: testHeader
|
|
spec:
|
|
headers:
|
|
customRequestHeaders:
|
|
X-Script-Name: "test"
|
|
customResponseHeaders:
|
|
X-Custom-Response-Header: "True"
|
|
```
|
|
|
|
```json tab="Marathon"
|
|
"labels": {
|
|
"traefik.http.middlewares.testheader.headers.customrequestheaders.X-Script-Name": "test",
|
|
"traefik.http.middlewares.testheader.headers.customresponseheaders.X-Custom-Response-Header": "True"
|
|
}
|
|
```
|
|
|
|
```yaml tab="Rancher"
|
|
labels:
|
|
- "traefik.http.middlewares.testheader.headers.customrequestheaders.X-Script-Name=test"
|
|
- "traefik.http.middlewares.testheader.headers.customresponseheaders.X-Custom-Response-Header=True"
|
|
```
|
|
|
|
```toml tab="File"
|
|
[http.middlewares]
|
|
[http.middlewares.testHeader.headers]
|
|
[http.middlewares.testHeader.headers.customRequestHeaders]
|
|
X-Script-Name = "test"
|
|
[http.middlewares.testHeader.headers.customResponseHeaders]
|
|
X-Custom-Response-Header = "True"
|
|
```
|
|
|
|
### Adding and Removing Headers
|
|
|
|
`X-Script-Name` header added to the proxied request, the `X-Custom-Request-Header` header removed from the request,
|
|
and the `X-Custom-Response-Header` header removed from the response.
|
|
|
|
Please note that is not possible to remove headers through the use of labels (Docker, Rancher, Marathon, ...) for now.
|
|
|
|
```yaml tab="Kubernetes"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: Middleware
|
|
metadata:
|
|
name: testHeader
|
|
spec:
|
|
headers:
|
|
customRequestHeaders:
|
|
X-Script-Name: "test" # Adds
|
|
X-Custom-Request-Header: "" # Removes
|
|
customResponseHeaders:
|
|
X-Custom-Response-Header: "" # Removes
|
|
```
|
|
|
|
```yaml tab="Rancher"
|
|
labels:
|
|
- "traefik.http.middlewares.testheader.headers.customrequestheaders.X-Script-Name=test"
|
|
```
|
|
|
|
```json tab="Marathon"
|
|
"labels": {
|
|
"traefik.http.middlewares.testheader.headers.customrequestheaders.X-Script-Name": "test",
|
|
}
|
|
```
|
|
|
|
```toml tab="File"
|
|
[http.middlewares]
|
|
[http.middlewares.testHeader.headers]
|
|
[http.middlewares.testHeader.headers.customRequestHeaders]
|
|
X-Script-Name = "test" # Adds
|
|
X-Custom-Request-Header = "" # Removes
|
|
[http.middlewares.testHeader.headers.customResponseHeaders]
|
|
X-Custom-Response-Header = "" # Removes
|
|
```
|
|
|
|
### Using Security Headers
|
|
|
|
Security related headers (HSTS headers, SSL redirection, Browser XSS filter, etc) can be added and configured per frontend in a similar manner to the custom headers above.
|
|
This functionality allows for some easy security features to quickly be set.
|
|
|
|
```yaml tab="Docker"
|
|
labels:
|
|
- "traefik.http.middlewares.testHeader.headers.framedeny=true"
|
|
- "traefik.http.middlewares.testHeader.headers.sslredirect=true"
|
|
```
|
|
|
|
```yaml tab="Kubernetes"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: Middleware
|
|
metadata:
|
|
name: testHeader
|
|
spec:
|
|
headers:
|
|
frameDeny: "true"
|
|
sslRedirect: "true"
|
|
```
|
|
|
|
```yaml tab="Rancher"
|
|
labels:
|
|
- "traefik.http.middlewares.testheader.headers.framedeny=true"
|
|
- "traefik.http.middlewares.testheader.headers.sslredirect=true"
|
|
```
|
|
|
|
```json tab="Marathon"
|
|
"labels": {
|
|
"traefik.http.middlewares.testheader.headers.framedeny": "true",
|
|
"traefik.http.middlewares.testheader.headers.sslredirect": "true"
|
|
}
|
|
```
|
|
|
|
```toml tab="File"
|
|
[http.middlewares]
|
|
[http.middlewares.testHeader.headers]
|
|
FrameDeny = true
|
|
SSLRedirect = true
|
|
```
|
|
|
|
### CORS Headers
|
|
|
|
CORS (Cross-Origin Resource Sharing) headers can be added and configured per frontend in a similar manner to the custom headers above.
|
|
This functionality allows for more advanced security features to quickly be set.
|
|
|
|
```yaml tab="Docker"
|
|
labels:
|
|
- "traefik.http.middlewares.testheader.headers.accesscontrolallowmethods=GET,OPTIONS,PUT"
|
|
- "traefik.http.middlewares.testheader.headers.accesscontrolalloworigin=origin-list-or-null"
|
|
- "traefik.http.middlewares.testheader.headers.accesscontrolmaxage=100"
|
|
- "traefik.http.middlewares.testheader.headers.addvaryheader=true"
|
|
```
|
|
|
|
```yaml tab="Kubernetes"
|
|
apiVersion: traefik.containo.us/v1alpha1
|
|
kind: Middleware
|
|
metadata:
|
|
name: testHeader
|
|
spec:
|
|
headers:
|
|
accessControlAllowMethods:
|
|
- "GET"
|
|
- "OPTIONS"
|
|
- "PUT"
|
|
accessControlAllowOrigin: "origin-list-or-null"
|
|
accessControlMaxAge: 100
|
|
addVaryHeader: "true"
|
|
```
|
|
|
|
```yaml tab="Rancher"
|
|
labels:
|
|
- "traefik.http.middlewares.testheader.headers.accesscontrolallowmethods=GET,OPTIONS,PUT"
|
|
- "traefik.http.middlewares.testheader.headers.accesscontrolalloworigin=origin-list-or-null"
|
|
- "traefik.http.middlewares.testheader.headers.accesscontrolmaxage=100"
|
|
- "traefik.http.middlewares.testheader.headers.addvaryheader=true"
|
|
```
|
|
|
|
```json tab="Marathon"
|
|
"labels": {
|
|
"traefik.http.middlewares.testheader.headers.accesscontrolallowmethods": "GET,OPTIONS,PUT",
|
|
"traefik.http.middlewares.testheader.headers.accesscontrolalloworigin": "origin-list-or-null",
|
|
"traefik.http.middlewares.testheader.headers.accesscontrolmaxage": "100",
|
|
"traefik.http.middlewares.testheader.headers.addvaryheader": "true"
|
|
}
|
|
```
|
|
|
|
```toml tab="File"
|
|
[http.middlewares]
|
|
[http.middlewares.testHeader.headers]
|
|
accessControlAllowMethods= ["GET", "OPTIONS", "PUT"]
|
|
accessControlAllowOrigin = "origin-list-or-null"
|
|
accessControlMaxAge = 100
|
|
addVaryHeader = true
|
|
```
|
|
|
|
## Configuration Options
|
|
|
|
### General
|
|
|
|
!!! warning
|
|
If the custom header name is the same as one header name of the request or response, it will be replaced.
|
|
|
|
!!! note
|
|
The detailed documentation for the security headers can be found in [unrolled/secure](https://github.com/unrolled/secure#available-options).
|
|
|
|
### `customRequestHeaders`
|
|
|
|
The `customRequestHeaders` option lists the Header names and values to apply to the request.
|
|
|
|
### `customResponseHeaders`
|
|
|
|
The `customResponseHeaders` option lists the Header names and values to apply to the response.
|
|
|
|
### `accessControlAllowCredentials`
|
|
|
|
The `accessControlAllowCredentials` indicates whether the request can include user credentials.
|
|
|
|
### `accessControlAllowHeaders`
|
|
|
|
The `accessControlAllowHeaders` indicates which header field names can be used as part of the request.
|
|
|
|
### `accessControlAllowMethods`
|
|
|
|
The `accessControlAllowMethods` indicates which methods can be used during requests.
|
|
|
|
### `accessControlAllowOrigin`
|
|
|
|
The `accessControlAllowOrigin` indicates whether a resource can be shared by returning different values.
|
|
The three options for this value are:
|
|
|
|
- `origin-list-or-null`
|
|
- `*`
|
|
- `null`
|
|
|
|
### `accessControlExposeHeaders`
|
|
|
|
The `accessControlExposeHeaders` indicates which headers are safe to expose to the api of a CORS API specification.
|
|
|
|
### `accessControlMaxAge`
|
|
|
|
The `accessControlMaxAge` indicates how long a preflight request can be cached.
|
|
|
|
### `addVaryHeader`
|
|
|
|
The `addVaryHeader` is used in conjunction with `accessControlAllowOrigin` to determine whether the vary header should be added or modified to demonstrate that server responses can differ beased on the value of the origin header.
|
|
|
|
### `allowedHosts`
|
|
|
|
The `allowedHosts` option lists fully qualified domain names that are allowed.
|
|
|
|
### `hostsProxyHeaders`
|
|
|
|
The `hostsProxyHeaders` option is a set of header keys that may hold a proxied hostname value for the request.
|
|
|
|
### `sslRedirect`
|
|
|
|
The `sslRedirect` is set to true, then only allow https requests.
|
|
|
|
### `sslTemporaryRedirect`
|
|
|
|
Set the `sslTemporaryRedirect` to `true` to force an SSL redirection using a 302 (instead of a 301).
|
|
|
|
### `sslHost`
|
|
|
|
The `sslHost` option is the host name that is used to redirect http requests to https.
|
|
|
|
### `sslProxyHeaders`
|
|
|
|
The `sslProxyHeaders` option is set of header keys with associated values that would indicate a valid https request.
|
|
Useful when using other proxies with header like: `"X-Forwarded-Proto": "https"`.
|
|
|
|
### `sslForceHost`
|
|
|
|
Set `sslForceHost` to true and set SSLHost to forced requests to use `SSLHost` even the ones that are already using SSL.
|
|
|
|
### `stsSeconds`
|
|
|
|
The `stsSeconds` is the max-age of the Strict-Transport-Security header.
|
|
If set to 0, would NOT include the header.
|
|
|
|
### `stsIncludeSubdomains`
|
|
|
|
The `stsIncludeSubdomains` is set to true, the `includeSubdomains` will be appended to the Strict-Transport-Security header.
|
|
|
|
### `stsPreload`
|
|
|
|
Set `stsPreload` to true to have the `preload` flag appended to the Strict-Transport-Security header.
|
|
|
|
### `forceSTSHeader`
|
|
|
|
Set `forceSTSHeader` to true, to add the STS header even when the connection is HTTP.
|
|
|
|
### `frameDeny`
|
|
|
|
Set `frameDeny` to true to add the `X-Frame-Options` header with the value of `DENY`.
|
|
|
|
### `customFrameOptionsValue`
|
|
|
|
The `customFrameOptionsValue` allows the `X-Frame-Options` header value to be set with a custom value.
|
|
This overrides the FrameDeny option.
|
|
|
|
### `contentTypeNosniff`
|
|
|
|
Set `contentTypeNosniff` to true to add the `X-Content-Type-Options` header with the value `nosniff`.
|
|
|
|
### `browserXssFilter`
|
|
|
|
Set `browserXssFilter` to true to add the `X-XSS-Protection` header with the value `1; mode=block`.
|
|
|
|
### `customBrowserXSSValue`
|
|
|
|
The `customBrowserXssValue` option allows the `X-XSS-Protection` header value to be set with a custom value.
|
|
This overrides the BrowserXssFilter option.
|
|
|
|
### `contentSecurityPolicy`
|
|
|
|
The `contentSecurityPolicy` option allows the `Content-Security-Policy` header value to be set with a custom value.
|
|
|
|
### `publicKey`
|
|
|
|
The `publicKey` implements HPKP to prevent MITM attacks with forged certificates.
|
|
|
|
### `referrerPolicy`
|
|
|
|
The `referrerPolicy` allows sites to control when browsers will pass the Referer header to other sites.
|
|
|
|
### `isDevelopment`
|
|
|
|
Set `isDevelopment` to true when developing.
|
|
The AllowedHosts, SSL, and STS options can cause some unwanted effects.
|
|
Usually testing happens on http, not https, and on localhost, not your production domain.
|
|
If you would like your development environment to mimic production with complete Host blocking, SSL redirects, and STS headers, leave this as false.
