Reference

add map

Add an entry to a Map file.

Description Jump to heading

A Map file contains a list of key-value pairs. You can reference the file on an acl line by using the -M and -f /path/to/file flags. Use add map to add a new entry to a Map file. Note that this only adds it to the load balancer’s runtime memory and not to the file on disk.
