Hi,
How does nginx balances traffic to upstream with different weight?
If I have 3 servers in upstream, with weight 1, 2, 4, assuming all are
healthy, will nginx send traffic to server 1, 2, 3, 2, 3, 3, 3 or 1, 2,
2, 3, 3, 3, 3?
If I have two servers with both weight 50, will nginx will 50 requests
to server 1, and then 50 to server 2, or will it calculate the ration
to be 1:1 and send one after another?
You can find a explanation of the algorithm in the commit messages.

I have found this with this query.
http://hg.nginx.org/nginx/log?rev=weight
Have you seen this doc?
