Generic redirect from{domain} to other servers

We have nginx server that redirect service requests by server name using proxy pass to upstream:

nginx conf:

server {

location / {

proxy_pass http://Requestsproxy-Rest;

and the upstream file:

server max_fails=4 fail_timeout=1s weight=1;

server max_fails=4 fail_timeout=1s weight=1;


We want to create haproxy that service(service) to be able to be accessed via “{service}” and the haproxy will forward/redirect the request to different address by the {service} to the nginx.

how do you think we can manage it via haproxy configurations?

Thanks in advanced.
