Load balancing using HTTP redirect reponse

This May I wrote a simple HTTP load balancer using HTTP 302 redirect response based on Facebook Tornado, it's called rbalancer  
After running it for 2 months, I'm confidence that it's stable and quite good for some purpose.
This's a short introduction of rbalancer:

rbalancer is a simple HTTP load balancer using HTTP 302 redirect response with round-robin and weighted random support built ontornado. rbalancer can perform health check on server in balancer list, when a server went down, rbalancer will automatic re-balance request to alive servers. When dead one goes up, it will be added to cluster and serving request likes normal
