Removing headers from backend response

  • Updated

You can remove headers from any backend response. This may be necessary if your application automatically sets headers. For example, Drupal can set the following Expires and Cache-Control headers to prevent caching:

1
2
3

Expires: Sun, 19 Nov 1978 05:00:00 GMT
Last-Modified: Wed, 18 Jul 2012 18:52:16 +0000
Cache-Control: no-cache, must-revalidate, post-check=0, pre-check=0

To remove a header from the backend response, add a new header as follows:

  1. Log in to the Fastly web interface and click the Configure link.
  2. From the service menu, select the appropriate service.
  3. Click the Edit configuration button and then select Clone active. The Domains page appears.
  4. Click the Content link. The Content page appears.

  5. Click the Create header button. The Create a header window appears.
