Hi list, I'm having issues using apache trafficserver as mid-tier cache / in forward mode. The request flow is as following "client" -> "trafficserver-reverse" -> "trafficserver-forward" -> "origin".
I would like to always keep the original client host header. On the reverse proxy this works fine by setting "proxy.config.url_remap.pristine_host_hdr" to 1. The forward proxy also receives the correct host header from the reverse proxy. But as soon as the forward proxy requests the origin server, it set's the host header to the "origin" name. In practice this looks like this: "client" -> "trafficserver-reverse" -> "trafficserver-forward" -> "origin" Host: example.org -> Host: example.org -> Host: origin.example.org If it matters: The forward proxy acts only as forward proxy and has reverse proxying disabled. Is there a way to ensure the host header is not touched trafficserver in forward mode? Thanks in advance, Matthias
