Nginx would need to support persistent connections to upstreams. What is the
status of that feature? Its been listed on the feature request page in the
wiki for a while.
I would be very interested to see support for persistent connections to
upstreams, and the company I'm working for would be willing to
(co)sponsor such a feature. I already contacted Evan Miller about this,
but he doesn't have enough time to pick this up currently. Anyone else
capable of and willing to pick this up?
