Table: HTTP socket directives
Directive Explanation
lingering_close It specifies how a client connection will be
kept open for more data.
lingering_time In connection with the lingering_close
directive, this directive will specify how
long a client connection will be kept open
for processing more data.
lingering_timeout Also in conjunction with lingering_
close, this directive indicates how long
NGINX will wait for additional data before
closing the client connection.
reset_timedout_connection With this directive enabled, connections
that have been timed out will immediately
be reset, freeing all associated memory. The
default is to leave the socket in the FIN_
WAIT1 state, which will always be the case
for keep-alive connections.
send_lowat If non-zero, NGINX will try to minimize
the number of send operations on client
sockets. It is ignored on Linux, Solaris, and
Windows.
send_timeout Sets a timeout between two successive write
operations for a client receiving a response.
