[edit] scgi_next_upstream

syntax: scgi_next_upstream error|timeout|invalid_header|http_500|http_503|http_404|off

default: scgi_next_upstream error timeout

context: http, server, location

This directive defines in which cases request will be passed to the next server:

It should be clear that passing request to the next server is possible only if no data have been yet returned to the client. So, if the error or timeout occurred during the data transmission to the client it's too late to fix it.
