Dynamically backend server

nandezddh

Hey. Your project is very great.
I have many questions. I have one file. it contains like this :

192.168.2.3
192.168.3.5
192.168.7.8

is it possibly to change backend server dynamically from that file without restart nginx??
Thank anyway. And sorry for bad english :D

If you are using ngx_lua's cosocket API (or one of those lua-resty-*
libraries based on that), you can do this with ease by just a few
lines of Lua :)

Sorry, last question. Is it possible to count how many active connection on backend server ? Thank you.

Well, I think such requirements can be easily fulfilled by external
tools like netstat. Just filter out the connections to the endpoints
you're interested in *and* in the ESTABLISHED state, and then count
the lines with the "wc" utility.
