add acl

Add a value to an ACL expression or file.

Description

An ACL is split into four parts:

  • a name for the ACL, which you choose

  • a fetch to collect information from the client's session

  • optional flags

  • a value to match against

In the example below, we mark these parts:

frontend www
   bind :80
   #   name       fetch  flags       value
   acl static_url  path   -i -m beg   /images/

Here, there is initially one value, /images/. Use add acl to add another value.

You can also store values in a file and then reference that file in an acl statement by using the -f /path/to/file flag. Use the add acl command to add a new entry to the file. Note that this only adds it to HAProxy Enterprise's runtime memory and not to the file on disk.

Examples

Use add acl to add the value /scripts/. Specify the acl file using either the path or the ID. Here we specify the ID of the ACL:

$ echo "add acl #0 /scripts/" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.4/hapee-lb.sock

This updates the ACL so that it represents this expression:

frontend www
   bind :80
   acl static_url path -i -m beg /images/ /scripts/

In the next example, we add the value /stylesheets/ to the ACL file /etc/hapee-2.4/paths.acl.

$ echo "add acl /etc/hapee-2.4/paths.acl /stylesheets/" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.4/hapee-lb.sock
