nginx: src/event/ngx_event

annotate src/event/ngx_event_udp.c @ 7393:4698cede59ff

Stream: proxy_requests directive. The directive allows to drop binding between a client and existing UDP stream session after receiving a specified number of packets. First packet from the same client address and port will start a new session. Old session continues to exist and will terminate at moment defined by configuration: either after receiving the expected number of responses, or after timeout, as specified by the "proxy_responses" and/or "proxy_timeout" directives. By default, proxy_requests is zero (disabled).
