Well, I am in no way an expert, but it seems to me that you could use
simply HTB on your outgoing ethernet link, create a class with rate
equal to ceil and equal to the greater bandwidth you will ever HTTP
allow to eat. Create another class to be the default one and let it grow
up to your link's bandwidth borrowing from HTTP traffic when there is
not 400 Mbps of them.

Then create a couple of filters to send traffic to the correct classes
and, maybe, attach a "sfq" qdisc to your HTTP and default leaves to 
guarantee fairness for individual connections.

Hope it helps.
