Yes with 1.6 and "http-reuse". You may need to specify "http-reuse aggressive" or "http-reuse always" so that even the first request may reuse a connection. Be aware however that in 1.6 no orphaned connections may remain, so at some point each server-side connection has to belong to a client-side one. When you get enough traffic to care about connection reuse, you never see the situation where you have zero concurrent connections, so it's not a problem, however it can be confusing during unit tests!
