HA v. 2.4.12

**Frontend** :  
`use_backend %[hdr(host),lower,map_dom(/etc/haproxy/Maps/domains.map)]`

**domains.map** :

```auto
domain.com srv
sub1.domain.com srv1
sub2.domain.com srv3

```

Now, calling [anysub.domain.com](http://anysub.domain.com) only matches the first occurrence of map ‘[domain.com](http://domain.com)’  
What would be the right syntax for an exact match? `map_beg`, `map_end` or `map_str` ?

Also wonder, whether can point to multiple map files (due to better organization) at same front end?
