Is it absolutely necessary to resolve the content staging ASMX over the DNS name? The request gets routed to a single server anyways.
For security reason, we've actually disabled the ability to resolve the ASMX via DNS. The reason is due to Kentico's requirement for the ASMX to be publicly resolvable. We've setup server-side routing rules to deny request to the ASMX against the DNS. We only allow the staging content ASMX to be resolvable via the internal server name.
What troubles me is that even with a clear cache on one of the server, it doesn't seem to refresh the database originated content. What would cause that?
