isn't this just a keepalive on the socket? no content actually being requested? If so I don't really see the problem. I had to write a reverse proxy the other day in nodejs to handle an unusual set of requirements that couldn't be satisfied by nginx\HAProxy and I did exactly the same thing - use an httpagent to keep connections alive to clients for a period of time (I think I chose 10 minutes or thereabouts) - without it sequential requests are about 10x slower due to SSL key calc overhead.
