The HTTP Response Headers module allows to set HTTP response headers (both standard and non-standard) on pages by various visibility rule settings. Headers can be restricted by path, content type and user role.

This module contains a sub-module, HTTP Response Headers UI, that lets you add, remove, and edit headers. Typically you would enable this module, perform your configuration, then disable it for day-to-day use.

Installation

  • Install this module using the official Backdrop CMS instructions.

  • Visit the configuration page under Administration > Configuration > System >
    HTTP Response Headers (admin/config/system/http_response_headers) to enable headers.

  • To set specific headers and set rules for their appearance, install the HTTP Response Headers UI sub-module and visit its configuration page at Administration > Configuration > System >
    HTTP Response Headers > List Rules (admin/config/system/http_response_headers/list) to add, edit, and/or remove headers and to set their visibility conditions.

Typical use cases:

  1. Set 'Cache-Control' or 'Expires' header to set/reset cache behavior
    of browser/cache servers.
  2. Set 'X-Frame-Options' to restrict your pages rendering on a frame.
  3. Set 'WWW-Authenticate' to set authentication to pages.

Note that if you set the Content-Security-Policy: frame-src header, you need to include your own site as an allowed host or it will break some functionality (e.g., AJAX file uploads).
