Can I redirect a domain url from within a listen section of a configuration

I am pretty new to HaProxy & still get stuck on proper cfg files. I wish I had a good place to configure a demo site. I feel like I would be better if I just experimented more. I am trying to do an entire domain redirect like would get redirected to

I am trying to determine if I am able to add a domain url redirect to a listen section of a configuration. My listen section looks like this:

Listen classic.mysite
     redirect scheme https is !{ ssl_fc}
     bind ssl crt /etc/haproxy/combined.pem
     mode http
     option tcplog
     http-request set-header X-Forwarded-For %[src]
     balance source
     option httpchk HEAD /farm-stage.aspx HTTP/1.1\r\nHost:\
     http-check expect status 200
     http-check disable on 404
     maxconn 10000
     server prodweb1 maxconn 5000 check fail 5
     server prodweb2 maxconn 5000 check fail 5
     server prodweb3 maxconn 5000 check fail 5
     server prodweb4 maxconn 5000 check fail 5
     server Server-SiteDown backup maxconn 5000

Am I able to add a redirect or ACL into my listen location? What would it look like? If not then what is the proper way to do this? I found that adding an ACL will work well. But I would need to have a backend config to point to? that means that my config would need over-hauled & I am still not sure it would work.

I appreciate your knowledge & patience.
Thank you in advance!
