Does the proxy_next_upstream “timeout” apply to both connect timeout and
Is it possible to configure proxy_next_upstream to use connect timeout
only, not the read timeout? In case a connection is made and the request
sent, I don’t want to re-try next upstream even when the read timeout
happens. Retry in this case could cause damage to the upstream
Can someone also give some example of “error” or “invalid_header”? Are
100% safe, meaning not causing upstream to process the request twice? Am
right that the only real safe is the connect timeout?
