failover to the next upstream server if one of the servers is slow

[ebondar]

Thanks itpp2012, I'll look at LUA

if I understand correctly, we can not specify the timeout of the session to
upstream the server, initiate a timeout error, and force requests to move to
another server?

 proxy_read_timeout 1;
-> proxy_next_upstream     error timeout
