Redirect a specific URL

Hello guys

I have a HAProxy in front of my servers.

Here is its config:

global
	log /dev/log	local0
	log /dev/log	local1 notice
	chroot /var/lib/haproxy
	stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
	stats timeout 30s
	user haproxy
	group haproxy
	daemon

	# Default SSL material locations
	ca-base /etc/ssl/certs
	crt-base /etc/ssl/private

	# See: https://ssl-config.mozilla.org/#server=haproxy&server-version=2.0.3&config=intermediate

frontend https
    bind *:443

    default_backend https

    balance roundrobin
    mode tcp

    mode tcp
    server worker1 172.16.0.172:32080 check
    server worker2 172.16.0.196:32080 check
    server worker3 172.16.0.153:32080 check

frontend stats
   option http-use-htx
   stats enable
   stats uri /stats
   stats refresh 10s

Now I want this (default_backend) but also add a rule to redirect xxx.company.com to another backend (And redirect everything other than that to the default backend).

How can I achieve this?

The solutions I tried (Not working):

frontend http
   bind *:80
   mode tcp
   redirect scheme https code 301 if !{ ssl_fc }
   acl test_host hdr(host) -i xxx.company.com
   use_backend xxx if test_host
   default_backend http

backend xxx
    balance roundrobin
    mode tcp
    server nginx 172.16.0.32:80 check

And

frontend http
   bind *:80
   mode tcp
   redirect scheme https code 301 if !{ ssl_fc }
   use_backend xxx if { hdr_dom(Host) -i xxx.company.com }
   default_backend http

backend xxx
    mode tcp
    server nginx 172.16.0.32:80 check
