# 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
|
|
|
|
??? example "File"
|
|
|
|
```toml
|
|
[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"
|
|
```
|
|
|
|
??? example "Docker"
|
|
|
|
```yml
|
|
a-container:
|
|
image: a-container-image
|
|
labels:
|
|
- "traefik.http.middlewares.testHeader.Headers.CustomRequestHeaders.X-Script-Name=test",
|
|
- "traefik.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.
|
|
|
|
??? example "File"
|
|
|
|
```toml
|
|
[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"
|
|
```
|
|
|
|
??? example "Docker"
|
|
|
|
```yml
|
|
a-container:
|
|
image: a-container-image
|
|
labels:
|
|
- "traefik.http.middlewares.testHeader.Headers.CustomRequestHeaders.X-Script-Name=test",
|
|
- "traefik.http.middlewares.testHeader.Headers.CustomResponseHeaders.X-Custom-Response-Header=True",
|
|
```
|
|
|
|
### 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.
|
|
|
|
??? example "File"
|
|
|
|
```toml
|
|
[http.middlewares]
|
|
[http.middlewares.testHeader.headers]
|
|
FrameDeny = true
|
|
SSLRedirect = true
|
|
```
|
|
|
|
??? example "Docker"
|
|
|
|
```yml
|
|
a-container:
|
|
image: a-container-image
|
|
labels:
|
|
- "traefik.http.middlewares.testHeader.Headers.FrameDeny=true",
|
|
- "traefik.http.middlewares.testHeader.Headers.SSLRedirect=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.
|
|
|
|
### 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.
