Set originRequest httpHostHeader

[ChrispyBacon-dev]

Support for httHostHeader
tunnel: your-tunnel-UUID
credentials-file: /etc/cloudflared/your-tunnel.json

ingress:

• hostname: service.domain.tld
  service: http://localhost:8000
  originRequest:

  Force the Host header that reaches Django to be exactly this:

  httpHostHeader: service.domain.tld

  (Optional) If your upstream is HTTPS, you can disable TLS verify:

  noTLSVerify: true

... fallback rule

• service: http_status:404

On that note, additional application settings?

Can be done via originRequest within config

Or these parameters in config.yml

I'm bumping into this as well. I need to be able to pass the internal domain name to a container when access it though CF using the httpHostHeader parameter.

[ChrispyBacon-dev]

Yes, a fix for this issue and another one (regex) will be added soon. Testing it locally build currently.

You, sir, rock. Cheers.

OK I pushed to stable branch. Docker image tag v1.9.2. added support for httpHostHeader Support with label and manual ingress rule via web UI.

[1.9.2] - 2025-06-25

Added

• HTTP Host Header Support: Implemented support for the new dockflare.httpHostHeader Docker label, allowing users to override the Host header sent to their origin service. This feature is also fully supported for manual ingress rules via the web UI (Add/Edit modals and display in the Managed Rules table). Applies only to HTTP/HTTPS services.
