Hi,<br>
<br>
How does nginx balances traffic to upstream with different weight?<br>
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?<br>
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?<br>
