In a configuration that share the same acl across all the frontends and backends like this example one:

```
frontend front1
        ...
        acl static1 path_end .jpg .gif .png .js .css .svg
        http-request ... if static1
        ...
backend back1
        ...
        acl static1 path_end .jpg .gif .png .js .css .svg
	    ignore-persist if static1
        ...
backend back2
        ...
        acl static1 path_end .jpg .gif .png .js .css .svg
	    ignore-persist if static1
        ...

```

Is there an alternative to avoid define the list of file extensions (in this case) each time?

Thanks,

Hi,  
You can load an acl from a file.  
Check the -f flag: [https://cbonte.github.io/haproxy-dconv/2.0/configuration.html#7.1](https://cbonte.github.io/haproxy-dconv/2.0/configuration.html#7.1)
