title: How to move database calls to application server behind a firewall
body: <p>I would like to use BreezeJS for data access in a Durandal SPA.  I have the initial app set up and working fine and uses a MVC 5 backend.</p>
  
  <p>However, one of the requirements is that the public IIS server is not making calls directly to the database.  In other words, the Breeze controller should call another IIS server which is behind a firewall which then connects to Sql Server.</p>
  
  <p>Is this possible, and if so, what is the basic architecture?</p>
