Add an entry to a Map file.
A Map file contains a list of key-value pairs. You can reference the file on an
acl line by using the
-f /path/to/file flags. Use
add map to add a new entry to a Map file. Note that this only adds it to HAProxy Enterprise's runtime memory and not to the file on disk.
In this example, the key foo.example.com and value be_bar are added as a new line in the file /etc/hapee-1.8/maps/hosts.map.
$ echo "add map /etc/hapee-1.8/maps/hosts.map foo.example.com be_bar" | socat stdio tcp4-connect:127.0.0.1:9999
