This is looking pretty good so far. Anyone know if you can do a weight round-robin scheme with this? If I treat every server the same the smaller ones would get flooded in no time.
If you mean for the proxying, not yet. For the 0MQ handlers it definitely does, but some folks also want to do blocking before sending to the backends.
We've basically laid down the core features and then we'll start planning things like this. Page caching, different proxy backend schemes, filters, handlers, etc.
