But caching servers only cache the result of a query.
for example a domain request
<A><A'>.example
the .example ns would internally match it with
<a><a>.example
and reply with a positive response.
the caching server will therefore cache
<A><A'>.example
with the response.
If you are asking what happens if another request comes:
<a><A'>.example
then the answer is simple, it will consult the .example server again,
then it will cahce
<a><A'>.example
with the response.
So, I dont see why all the servers in the world needs to be able to handle
all additional matching rules.
