Best Practice for internal client Connectivity with Horizon View 6

Hi All,

I have View setup with a Connection and Security server.  Internal clients connect directly to the connection server for authentication, while external clients go thru the Security server.  Recently, a friend of mine and I were debating our setups.  He has all of his traffic going to the Security server.  His setup seems to be supported by the latest diagrams in the View 6 documentation.  What is the best practice?

Thanks!
