Headers

The Headers App allows to define custom HTTP headers to write to requests or responses through Webfuse as a web proxy. It can be utilised for for security enhancements, compliance enforcement, tracking control, and feature modifications – all without changing the underlying web application.

Format

To configure the App you will need to specify the format of the header in JSON format, specifying a key a value and a type which can be of “response” or “request”

Example

To prevent any app from getting access to a camera/microphone you could inject a Permission Policy header that explicitly forbids this:

[
  {
    "key": "Permissions-Policy",
    "value": "camera=(), microphone=()",
    "type": "response"
  }
]
