Hydra. So many Head(er)s.
=========================

[](#hydra-so-many-headers)

This extension allows to add response headers on a per site base without using TypoScript.

If you have only one set of response headers that you want your TYPO3 websites to send, it might be a good idea to configure the headers directly in your webserver. However, there might be the requirement that different sites inside the same TYPO3 system have to send different headers. In such a case, this extension provides the functionality to configure response headers in the site configuration.

Example
-------

[](#example)

In the site config simply specify the headers:

```
responseHeaders:
  Content-Security-Policy: "default-src 'self';"
  Referrer-Policy: "no-referrer-when-downgrade"
  X-Content-Type-Options: "nosniff"
  X-Xss-Protection: "1; mode=block"
  Feature-Policy: "camera 'none'; geolocation 'none'; microphone 'none'; payment 'none'"
  Permissions-Policy: "camera=(), geolocation=(), microphone=(), payment=()"
  X-Frame-Options: "SAMEORIGIN"
```

To improve maintainability of header configuration with many parts like CSP or Feature-policy each header can be configured as a list. The list items will be concatenated to one string when the header is added. The above example could be rewritten like this:

```
responseHeaders:
  Content-Security-Policy: "default-src 'self';"
  Referrer-Policy: "no-referrer-when-downgrade"
  X-Content-Type-Options: "nosniff"
  X-Xss-Protection: "1; mode=block"
  Feature-Policy:
    - "camera 'none';"
    - "geolocation 'none';"
    - "microphone 'none';"
    - "payment 'none'"
  Permissions-Policy:
    - "camera=(),"
    - "geolocation=(),"
    - "microphone=(),"
    - "payment=()"
  X-Frame-Options: "SAMEORIGIN"
```

Those headers will be added via a middleware to responses only for the corresponding site.
