This Elixir plug allows manipulation of HTTP response headers:

• Deleting one or more HTTP response headers.
• Setting one or more HTTP response headers.
• Setting the HTTP "Server" response header.

This plug supports the following options. At least one option must be specified.

• delete: a bitstring or a list of bitstrings of header keys to be deleted.
• server: convenience function for set: ["server": "MyServer"]
• set: a list of key/value pairs for headers to be set.

To use the plug in your projects, edit your mix.exs file and add the project as a dependency:

defp deps do
  [
    {:plug_response_header, "~> 0.2.1"}
  ]
end

pipeline :browser do
  plug PlugResponseHeader,
    delete: "x-request-id",
    server: "MyServer",
    set: [
      "strict-transport-security": "max-age=31536000",
      "cache-control": "no-transform"
    ]
    ...
end
