/**
 * Unit test for 6712778 ("Virtual Server's "hosts" parameter cannot be
 * dynamically changed").
 *
 * This unit test creates a virtual server with a "hosts" attribute equal to
 * "myhost", deploys a webapp to it, and accesses the webapp by specifying
 * a Host header equal to "myhost" in the request.
 *
 * The test then updates the virtual server's "hosts" attribute to 
 * "mynewhost", and ensures that the webapp may still be accessed when
 * specifying a Host header equal to "mynewhost" in the request.
