I am trying to setup HAProxy as a reverse-proxy for a nasty application that
really wants the Host: header on the backend request to match the hostname of
the backend system - It's a off-the-shelf app, so there is no opportunity to
make modifications to this.
So far I've got a rspirep to strip out 301/302 Location headers and put in the
HAProxy instance hostname, but on the backend I still have to replace Host:
with the backend server name. With only one backend server and a hard coded
reqirep header it works, however somehow I need a per-server reqirep
substitution.
As you allready noticed, you cant do that directly.
You can do it directly by using a trick with the "http-send-name-header"
keyword [1], with "Host" as the header name.
Then, be sure to name your backend servers with their hostname, and
that's it ;-)
Caution : there was a bug in haproxy-1.4, which is only solved in the
last snapshot, but it's OK in the 1.5 branch. From the configuration you
provided, I guess you're already in 1.5.
Example :
listen test :8888
mode http
option http-server-close
http-send-name-header Host
server server1.local 127.0.0.1:80
server server2.local 127.0.0.1:80
In this example, server1.local and server2.local are the values provided
in the Host header.
