How to define string list for comparison?

[Marco Pizzoli <marco.pizzoli@xxxxxxxxx>]

Hi list,

I'm using Apche 2.4.9 and I am trying to define a configuration by leveraging the <if> constructor.

In short I would like to trigger some configuration if the client IP matches one of a list I put up.

I think the "in" operator is what I need, but I'm just failing in understanding how could I implement a string list.

<If "%{REMOTE_ADDR} in my_string_list">

How can I define the string list? It's just a matter of understanding the syntax. 

On this page it is referred just a "string list" but I cannot find how to explicit that string list.

http://httpd.apache.org/docs/2.4/expr.html#other

I just need something like "1.1.1.1 2.2.2.2 3.3.3.3" and so on...

Any help?

Thanks in advance

Marco
