No, but I don't think it'll help much.  

Correct me if I'm wrong, but by the time you see the content in the
request fly by, the connection is already established.  By that time, it's
too late, since you've _already_ done the load balancing yes?

AFAIK, the only way to approach layer 7 switching is to accept the
connection and request on the switch itself, then replay it over a
connection between the switch and selected backend server -- sort of like
a proxy server, and how I believe ktcpvs works.

Thanks,
