sound normal. Thinking more about it I can't remember an example of
ini where order counts.

Yes current vhosts rules like the rewriter are relying on the order.
It sounds really complicated to have this working with  multiple ini
almost impossible, except if they are prefixed I think

It's easier to do. What doesn't work actually is the variable
replacement. I propose to remove these replacements and just use host
wildcard, simple path and host name. No wildcards in path. If we are
OK with that, I can attach the patch to jira during the we.
