Handling Upstream Connection Timeouts

[David Santhosh]

What's the better way to handle upstream connection timeouts. I am trying to add a custom header when upstream connection times out; tried to match it with 408 and still fails,

local status = ngx.status

if status == 408 then

  ngx.header["Connection-Timedout"] = "true"

end

Can you please help me here.
