Currently, I have a bunch of rules in haproxy.cfg like this:

frontend frontend-https  
bind 10.30.1.120:443  
redirect prefix [http://customerwebapp.com/redir.jsp?customer\_domain\_id=123](http://customerwebapp.com/redir.jsp?customer_domain_id=123) code 301 if { hdr(host) -m sub [example.com](http://example.com)  
}  
default\_backend backend-https

but I want to integrate a map file and take all the rules sets out with something like this:

frontend frontend-https  
bind 10.30.1.120:443  
redirect prefix (%[req.hdr(host),lower,map\_reg(/etc/haproxy/redirect.map)] code 301

}  
default\_backend backend-http

and the file would contain something like this  
(\w._.)?.customer.com(._) [https://webapp.com/redir.jsp?customer\_domain\_id=123](https://webapp.com/redir.jsp?customer_domain_id=123)

I know it’s missing the conditional, “if { hdr(host) -m sub [example.com](http://example.com)” but I’m not sure how to integrate them.

`https://webapp.com/redir.jsp?customer_domain_id=123` is not really a prefix, I assume you are going to use the correct redirect keyword in your real configuration.

You need to work with `http-request redirect` here instead.

Something like:

```
http-request redirect location %[req.hdr(host),lower,map_reg(/etc/haproxy/redirect.map)]
```

Thank you so much, Lukas!
