Hello,
if you return control to the nginx event loop while generating the response, you may set appropriate events to detect if the client closed the connection. See ngx_http_upstream_check_broken_connection() and related things in the ngx_http_upstream.c for an example. Yes, it’s fine, I will take a deeper look at upstream module to find out the answer. Thanks. Log module, once you use $bytes_sent (or $body_bytes_sent, as logged by default) variable, logs the number of bytes sent to the client. It is not the same as the number of bytes actually received by the client though, because there are bytes which are sent (i.e., passed by nginx to the socket buffer) but not yet received. Well, this means there’s another parameter in log module which actually log number of bytes client received (other than $body_bytes_sent or $bytes_sent). ? -- Hưng Email: hun...@opensource.com.vn > On Feb 12, 2015, at 8:52 PM, Maxim Dounin <mdou...@mdounin.ru> wrote: > > f you return control to the nginx event loop while generating the > response, you may set appropriate events to detect if the client > closed the connection.
