I am having some difficulty with nginx as a load balancer on MacOS X (Intel). I am running 0.5.19, but the problem occurs with recent earlier versions as well.
With "use kqueue" 2007/04/26 22:26:15 [info] 4133#0: *3048 kevent() reported that client 192.168.0.100 closed keepalive connection
With "use poll" 2007/04/26 22:59:48 [info] 10189#0: *375 client 192.168.0.100 closed keepalive connection
On the client side, I get a "Socket closed." error. My HTTP client is not configured to use keepalive, which makes the error message seem very strange. The only 'weird' thing I am doing is sending a '100 Continue' response from the back-end server. Does nginx have different behavior when I send back a 100?
Does the client do POST and pass "Expect: continue" ? nginx does not support "Expect: continue/100 Continue" dialog because current browsers still do not support it (at least I never see).
So the client askes "Expect: continue", nginx passes the request to backend, the backend responses "100 Continue". nginx sends it to the client and goes to keep-alive state.
The client is not passing Expect: continue. I'm mimicking the behavior of a 3rd-party app that 'unexpectedly' sends a 100 Continue response before the 'real' response code. These are POST requests though, yes.
In the nginx access log, '100' is the status code shown. Does nginx enable keep-alive automatically when that happens?
keep-alive in nginx has no relation to "100".
nginx enables keep-alive if keepalive_timeout >0 and *) an request has the "Connection: keep-alive" header 2* or an request has no "Connection" header and the request version is > 1.0.
OK, so if I set keepalive_timeout to 0, that should reveal whether this is actually the problem I am seeing?
