The current specification is inconsistent because you say in one place that the user data is stored in one place but in another that multiple locations are returned. If you want to allow direct access to the individual members of the virtual server, that's up to you (though it puts the burden of load-balancing on the Diameter server returning the Redirect-Host AVP). One way or the other the spec needs to be consistent. ... Hope this helps, ~gwz Why is it that most of the world's problems can't be solved by simply listening to John Coltrane? -- Henry Gabriel
