Code review comment for lp://qastaging/~cerberus/nova/lp820658

Brian, it's not currently possible to stack filters WSGI-style. Take a gander at the "choose_host_filter" method in host_filter.py. It instantiates the first filter it finds based on the name requested. I think that sounds like a pretty good use-case, but I'd rather we file a blueprint or bug for implementing that rather than trying to shoehorn that functionality in this patch.

Does that work for you?
