- * Description of the tests:
- *   Check that HSTS priming occurs correctly with mixed content
- *
- *   This test uses three hostnames, each of which treats an HSTS priming
- *   request differently.
- *   * no-ssl never returns an ssl response
- *   * reject-upgrade returns an ssl response, but with no STS header
- *   * prime-hsts returns an ssl response with the appropriate STS header
- *
- *   For each server, test that it response appropriately when the we allow
- *   or block active or display content, as well as when we send an hsts priming
- *   request, but do not change the order of mixed-content and HSTS.
- *
- *   Test use http-on-examine-response, so must be run in browser context.
