Multiple machines, need to add multiple domain names about varnish-http-purge HOT 3 CLOSED

You mean to have one domain (say www1.xyz.com) flush two or three other domains' caches?

The only possible use case I could think of there is a Multisite with mapped domains (or subdomains) where you'd want to flush the whole system cache at once, and if that's the case, it's beyond the scope of the plugin.

Yeah, I have a non-multisite with multiple domains serving 1 site for load balancing and want to flush all of them, so basically changing the 'Configure Custom Varnish IP' to an array. Is that within scope?

That would require a hell of a rewrite for a pretty weird situation that isn't even the best practice for load balancing (which would be one domain, multiple IPs). Horizontal scaling is a bit of a mess with WP anyway though...

But that rolls back to supporting multiple Varnish IPs, which I currently don't do because I don't have a good way to test that setup. I don't like to add 'unsupportable' aspects to my code, and since I can't dev or support multiple IPs at this time, I won't be adding that to the plugin. There are other plugins that can do what you're looking for though.
