How to get the current hostname in VCL?

If I use req.http.host in the src parameter of a header, I get the hostname of the backend.
How can I get the request hostname instead?

I’d like to not have to hardcode my domain.

Thanks!

  Hey @analogue, try req.backend.

  req.http.host pulls the inbound request Host header, so getting the domain for that is to be expected.

  I don't think my question was clear enough =)

  If I serve domain.com with Fastly, I'd like to get "domain.com" somewhere. Not the hostname of a backend.

  I solved this by setting a new variable: set req.http.original_host = req.http.host

  analogue in which subroutine you are setting set req.http.original_host = req.http.host.
