Load Balance on Windows 7 Pro Desktop

For development and testing purposes, I'd like to install two "web heads" and a database on my Windows 7 Pro desktop, and then round-robin the incoming requests between them. The basic setup is easy enou开发者_JS百科gh, but I have no good solution for distributing the requests between the two web heads.

Is there any load balancing solution that I can run on Windows 7 Pro?

P.S. I can setup Server OS VMs and use Windows Load Balancing, but it would be so much more convenient to have it all contained on my desktop machine.

You could try using perlbal as suggested here. Perlbal is pretty well respected, and perl runs well on windows, so it should be more than adequate. F5 also has a virtual appliance if you happen to be using BigIP in production.
