The Varnish documentation on ban is not exactly clear to me. It suggests only a bunch of variables and operators are allowed, but also hints TTL could be used.

What I would like to write is in the line of

ban obj.ttl<0

Which obviously only makes sense because I use a long grace period.

Also, why am I doing this? RAM issues.

Please answer the question without judgement on why, I’m inheriting stuff, I just need help on that very specific idea of mine.

Thanks
