to query the cache. If BIND did not have the information about tfn.net in its cache, would it go and retrieve the information and then decide that it was unable to give the cached information to the requester? Should the "query (cache) denied" message be produced? We were confused because we did not see any queries for tfn.net in the

Note that forcing a recompile will have no effect on the query's use of the data cache. One reason you can't just mark an individual query to avoid the cache is the cache use is an integral part of executing the query. If the data is already in cache, then what would SQL Server do with the data if it was read a second time?
A Cache Manager query is received by an OS-selected worker, just like any other HTTP request. The receiving worker forwards the query to the Coordinator process (via IPC). Coordinator sends the same query to each kid process (including the original query recipient and Coordinator itself), via IPC, one by one, and aggregates kids responses.
I know some people use WinSQL to connect to Cache and a Cache tech support person thought SSMS could perform the same role, but he doesn't use SSMS personally so didn't know how to configure the connection. Hence this post. If it's doable, I'd love to get my instance of SSMS configured so I could write queries directly against Cache.
